No you're wrong. I'm wasn't running any of those tools.

Thanks, but I get the following error trying to run that command, even though DPC_Interrupt.etl doesn't already exist! "xperf: error: NT Kernel Logger: Cannot create a file when that file already exists. (0xb7)."

No, there's no way for me to tell when the latency or ISR or DPC execution time goes too high without running LatencyMon, so it's impossible for me to know when to make a trace. The ataport.sys spike seems to have been linked to Truecrypt and hasn't reoccured since I closed that. ndis.sys is higher than ever though now at 0.69ms (netbt.sys is at 0.1ms and tcpip.sys is at 0.26ms) and the highest kernel latency is on the edge at 906us.

Dammit, ataport.sys just spiked to 2.86ms. Highest kernel latency is 858us.

Yeah I have, they're looking into it.

I think things are OK at the moment. I get brief breaks in sound with TV (which aren't replicated if I rewind and play that section again) but I don't think it's a latency issue as it doesn't happen when watching movie files. Cutscenes in games are OK now, but I still get quite a bit of brief freezing / stuttering when actually playing the game, but I guess it could just be the game loading data and something I have to put up with. I was just a bit bothered by ndis.sys and netbt.sys as they used to be much lower, and I'd like to use VMware workstation but last time I tried it, these two (and tcpip.sys) went much higher and I had bad video / audio problems again.

Oh well, looks like I'll have to try and work this out on my own. The ataport.sys does seem much better now, but I uninstalled some software as well so I'm not sure what fixed that. Really only ndis.sys and netbt.sys are too high (0.43ms) for my liking now. The next highest are USBPORT.sys 0.25ms, CLASSPNP.SYS 0.22ms, ntoskrnl.exe 0.18ms with everything else under 0.09ms

OK, thanks. EDIT: Actually that doesn't seem practical, as firstly ProcExp doesn't report high usage, so I'd have to sit staring at it for ages trying to catch a spike and also even if the CPU usage doesn't go high, I'm still seeing excessively high kernel latency and/or DPC and latency execution times in LatencyMon.

OK, but how do I identify high ISR or DPC execution time or high kernel latency with ProcExpl? This is what I'm seeing: And what commands do you want me to run to make the trace if the ones I posted from your original post are no good?

I did xperf -on latency -stackwalk profile and after seeing problems in LatencyMon xperf -d DPC_Interrupt.etl how can I know when "the high DPC and Interrupt usage occurs" if I don't run LatencyMon?

Here you go. I'm seeing absolutely atrocious DPC and ISR execution times now. _________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be having trouble handling real-time audio and other tasks.

The reviews I've read don't really show a major benefit (unless you need hotswapping or RAID) and there's complications like bootup apps (partition utilities, TrueImage) not working in AHCI mode, plus the whole hassle of switching to AHCI mode without ending up with a system that won't boot. Anyway, ataport.sys was OK with IDE mode before and I can't see that switching to AHCI mode is going to do anything about the USBPORT.SYS issues.

It's a SATA HDD in IDE mode.

Just the one HDD and in IDE mode (UDMA 6). I don't have any optical drives connected at the moment.

Hi I'm having trouble loading the symbols. I've installed xperf with the .NET Framework 4 SDK Web installer, so the process wasn't quite the same as on the page you linked to in your first post, but I installed WPT and Debugging tools under Common Utilities and WPT under Redistributable Packages. Might not have needed all those but wasn't sure. Anyway, that gives a Start Menu shortcut, Windows SDK 7.1 Command Prompt, so I used that and created the trace with xperf. Then I open it with WPA and change the NT_SYMBOL_PATH to srv*C:\symbols*http://msdl.microsoft.com/download/symbols tick Load Symbols and click on Summary Table, but everything's listed under Unknown. I might already have enough information from LatencyMon for you to go on though. I'm running Win7 x64 Ultimate SP1 on a MSI 990FXA-GD80 motherboard with Phenom II X4 955 processor and 8GB DDR3. I first found I was having dpc latency problems that were being caused by Outpost Security Suite, so I uninstalled that and installed Comodo Firewall instead. I also had to kill/disable the nusb3mon.exe utility, which brought the max execution time for USBPORT.SYS down from 1.3ms to 0.38ms. Later, I installed VMware Workstation (as I was having problems doing some things in Virtualbox so wanted to see if VMware worked better) and noticed problems again. I reduced them by disabling the two NICs that it installed, but had to disable all it's services as well to completely sort it out, so I uninstalled it. However, I'm still having problems. I notice if I open a browser (IE or Iron Portable) the execution time for ndis.sys jumps up to 0.5-0.8ms. Although LatencyMon reports that my system is still OK to play video with latency around 500us, I get spikes much higher (around 1100us) and ndis.sys can hit 1.35ms-2.8ms and then LatencyMon reports that my system isn't OK. With Outpost SS, tcpip.sys was the problem (around 0.7ms with spikes every 5 seconds), followed by ataport.sys and USBPORT.SYS. After getting rid of OSS, I tried disabling the two Standard Dual Channel PCI IDE Controllers (one of which is off a PCI standard PCI-to-PCI bridge) that don't have anything connected, the 1394 Controller, the AMD 6950 HD Audio, the two USB 3 Controllers, three Standard Enhanced PCI to USB Host Controllers and three Standard OpenHCD USB Host Controllers, but was still having a problem with USBPORT.SYS hitting 1.3ms: http://imageshack.us/photo/my-images/198/latencymonhighusb.png/ I then disabled nusb3mon.exe which brought it down to 0.38ms and moved my KVM from a USB3 port (running at USB2 I imagine considering what I'd disabled) to a USB2/SATA combo port, which brought it down to 0.25ms but I still had problems with ataport.sys: http://imageshack.us/photo/my-images/703/latencymonkvminusb2comb.png/ http://imageshack.us/photo/my-images/545/latencymonkvminusb2comb.png/ Then I transferred my KVM to a normal USB2 port, after which USBPORT.sys and ataport.sys didn't go above 0.25ms although uninstalling OSS seemed to have caused ndis.sys to increase from 0.03ms to 0.28ms http://imageshack.us/photo/my-images/16/latencymonkvminusb232mi.png/ http://imageshack.us/photo/my-images/594/latencymonkvminusb232mi.png/ However, since installing/uninstalling VMware I'm now having problems with ataport.sys again. I've still got all the devices listed above disabled, and still only have things plugged in the normal USB2 ports. http://imageshack.us/photo/my-images/37/latencymonafteruninstal.png/ http://imageshack.us/photo/my-images/259/latencymondriversafteru.png/ http://imageshack.us/photo/my-images/213/latencymonmainafterunin.png/ http://imageshack.us/photo/my-images/195/latencymondriversafteru.png/ I've just unplugged my USB hub (with only an Xbox360 controller plugged in) so that only my KVM is connected to a USB port, which may have brought the ataport.sys execution time down somewhat, but the latency's still rather high. http://imageshack.us/photo/my-images/337/latencymonmainmplivetvu.png/ http://imageshack.us/photo/my-images/864/latencymondriversmplive.png/

It is more probable that the BIOS doesn't expose the (possibly SATA) disk properly. What happens in "plain" grub4dos? Try pressing C to access command line, then issue a geometry (hd0) and a geometry (hd1) jaclaz Thanks, I'll try that next time I get my hands on her laptop

Just wanted to report a problem I had with this. I've got a stick that works fine to install XP to my two desktop PCs. My sister has a laptop with Vista on it and I shrunk the system partition to make room for XP, so that I could setup a dual-boot, but when I booted XP setup from the stick, it didn't detect the hard drive at all and only showed the stick as a possible install destination. I haven't had a chance to test whether installing from CD will work yet, so I'll report back when I have and also get the exact details of the laptop. Perhaps this is an already known situation where WinSetupFromUSB doesn't work, or maybe it's because the laptop HD has a Recovery partition as the first partition on the HD (which is probably quite common with laptops), but I thought I'd let you know in case it's something you want to look at.

Like I said, the USB stick boots fine, it's just when running PLOP it says "Cannot find NTLDR" because something's changed the bootsector (not the MBR) from Grub4DOS to NTLDR. I guess that means that PLOP loads the bootsector rather than the MBR. I did change the bootsector back to Grub4DOS and safely removed hardware and when I re-inserted the stick, it wasn't even recognised again in BootICE, which is strange. It does seem to have fixed the problem though as PLOP is no longer giving that error, so the bootsector must be staying as Grub4DOS. Regarding the nlite problem, I fixed this by taking out some Hotfixes (IE8 and WMP related I think) and rebuilding.

That's what nlite does with Direct Hotfix Integration enabled with individual updates as well as far as I can see. But yeah, it's probably easier to use an update pack.

First, nice one on v1.0. So much easier now. I'm having a weird problem though, when testing in Qemu v7.0 with my USB flashdrive. Firstly, I've got PLOP v5.09 in a PLOP folder on my USB, so I've amended the menu entry to "kernel /PLOP/plpbt.bin". The thing is, the bootsector on my flashdrive keeps changing from Grub4Dos to NTLDR, which causes PLOP to fail with a "Could not find NTLDR" error. I've just run WinSetupFromUSB (1.0 beta6) to install the files to my flashdrive, and it's changed after that. Qemu was loaded but not running (so the flashdrive wasn't mounted in it) during this time, so I can't see that Qemu could be responsible, but it doesn't seem that it's anything to do with WinSetupFromUSB either, as I've seen it happen after the first stage of the XP install, after the second stage and after loading LiveXP, but not consistently IE it doesn't always happen after any of those. It didn't happen after loading FreeDOS or USCD5 but I can't say it never would unless I keep trying loading them. I really can't make much sense of this, so if anyone's got an idea what might be causing it, please let me know. I'm also having trouble installing from an nLited source. Vanilla (unattended) XP installed in Qemu OK, but my nlited source just reboots at the second stage, or occasionally says "setup.exe - Unable to Locate Component. This application has failed to start because Normaliz.dll was not found. Re-installing the application may fix this problem.". I copied that file to Windows\System32 on the HD but it still rebooted the next time I restarted the second stage. I've attached my nlite last session in case anyone can spot anything in there that's causing the problem. I imagine it's most likely one of the Hotfixes. Last Session.ini

Fair enough. I know this is the usual advice but I thought perhaps it might be possible to do this. I'll just do as you suggest to avoid problems. Cheers.

As Windows Updates are constantly coming out, I was wondering if it's possible to run nLite again at a later date and update them, providing I don't use Direct Hotfix Integration (I'm assuming this is completely out of the question if I did use this option). So I've setup all the options and removed components, etc and added some hotfixes (with Direct Hotfix Integration disabled, so that they go in the SVCPACK folder). Can I then go back and select only the Hotfixes, Add-ons and Update Packs button, disable Direct Hotfix Integration and add all the Windows Updates I've downloaded with Windows Update Downloader (which will include some of the updates I added on the first run) to keep my nlite'd XP up to date? I presume I should empty the SVCPACK folder before doing this. If I also added some program addons on the first run, is there a way to remove these. I've just tried doing this process and even though I've deleted the program addons from the SVCPACK folder, it still references them in the new SVCPACK.IN_ in the [setupHotfixesToRun] section, even though I didn't load a Preset or Last Session, so it's clearly not that simple.

I do normally but unfortunately I've got too many other things to fix to take on any more at the moment If I could just get PLOP working with my hardware, to speed up loading the RAM image from USB, I'd be happy.
