wtf(!) I'm ready to pull my hair out. Just did (yet another) clean install, but somethin' aint right. Been working on an unattended install, using nLite... SP2 slipstreamed, hotfixes, coupla registry tweaks, a few patched dll's... Lotsa s***e changed (over and over again), but not so much between my last test build and this one. I just changed up to nLite 1.0 RC2 (from RC1), and I think that was it... aside from adding a WGA dll... anyway... the freaking network throughput sux rocks! And I'm not figuring out why or what to do about it. I can DL files off the internet faster than I can on the LAN! WTF is up with that?!?! Less than 1%... we're talking about an average of around 30KB on the LAN, using sftp. Receiving. Sending a file, easy 10Mb or better. 100Mb LAN. So messed up... Using pcattcp, I can send at about 83Mb. Sounds about right to me. Receiving is at about .75Mb. (!!!) Fark! What I don't know, obviously, is what the heck changed between my last build and this, if anything... something changed, somewhere, because I wasn't having this trouble on my last install, but golly- I wasn't keeping track of every last detail. It's an A8N-SLI with the 6.70 NVIDIA UDA. That's the drivers used for the last 2-3 builds. They seemed to work fine before. Chipset set to 100/full. Static IP. I've checked my cables, I've reinstalled, I've tried various tweaks of the tcpip stack, I've tried kicking the computer and spitting on it, as well as swearing at it, I've even threatened it. Anyway. Not that I'm truly expecting to find an answer here- but I thought I'd vent and hope that maybe, just maybe, someone might receive a premonition or something, about my problem, and be able to impart wisdom.
