Slow Network File Transfer Speed

[ripken204]

i am trying to send a few gigs of files from my desktop to my laptop.

both are using vista ultimate x64

the problem is that the transfer speeds are like 250kb/s or less...

now that is just slow!

they are both wired to the same router.

any ideas?

disabling the windows firewall on both did nothing

well apparantly the problem is only when copying alot of very small files.

i am currently testing copying a large iso and it is going at 11MB/s

this is wired, but 11MB/s still is slow..

what speeds do you guys transfer at?

wireless, the same large iso transfers at 550KB/sec...

i suppose it is the wireless b router, lol. very old stuff. i should probably get that upgraded.

Unless you have a Gigabit router, you can't expect more.

[PC_LOAD_LETTER]

you could expect up to 100mb. i doubt the router maxes out at 10base. If you have a large amount of files to move and the pcs arent far from each other, just make a crossover cable and wire the 2 PCs in their own lan and if both card are GBit cards, you can see up to 1000Mb

the other thing to try is see if the cards are being incorrectly set to 10Mbps

Network Connection->Properties on the ethernaet adapter->Configure->Advanced Tab->Speed & Duplex-->set it to 100Mbps Full duplex(or 1.0Gbps Full Duplex if your router is Gbit) -you may have to repair the connection for it to take affect.

do that on both machines and see if your speeds improve. if you lose connection after changing that value, just move it down to to 100 Half Duplex and if it stil doesnt work, just change it back to auto negotiation

i just set everything ot 100MB full and speeds didnt change

still transferring at 11-12MB/s for single large files and 500KB/s for many small files

i guess i will have to try a different router.

i'll go over to my friend's house later and test how his is, i think he has g, he better..

LOL. Fast Ethernet is 100 Megabits.

If you force a network interface to full duplex make sure you do that for every device on the network or not at all. Otherwise duplex mismatch will occur.

i said everything..

That sounds like a fairly reasonable throughput for a 100Mbps network to be honest.

100Mbps = 100,000,000 bits/sec

100,000,000 bits / 8 = 12,500,000 bytes/sec = 12.5 MB/s

12,500,000 / 1,024 / 1,024 = 11.9 MiB/s

This is theoretical maximum throughput, then there is the overhead of breaking the raw data into packets and adding headers, so you would expect it to be less than either 12.5 or 11.9, depending on which "standard" for MB you are using

802.11b is 11Mbps = 11,000,000 bits/sec = 1,375,000 bytes/sec

= 1.375 MB/s or 1.311 MiB/s theoretical maximum, but then signal strength, encryption overhead, latency and other traffic will have a significant effect.

Be aware that typically, users of GigE switches find ~220Mbps is their actual raw throughput - it's not quite as impressive as the often-expected 1000Mbps.

eh, that sucks. at least i have an explanation, thanks.

i might get a new router tonight:

have an a/b/g/n wireless card wit a 5 year old b router... that just isnt fun.
