Gigabyte Lan file transfer slow

post #1 of 17
Thread Starter 
Hi guys... just built myself a home server.. i'm using a gigabyte lan switch.. all cat6 cables.. the thing is that my lan usage for file transfer is only hitting 50% ish.. the funny thing is that the lan usage will hit 99% when i copy files from the server to my computer... but not vise versa.. when i try to transfer files from my computer to the server (which i mainly does), the speed is only 50%.. anyone know why??

My first guess would be hard drive write bottleneck on the server. What is the server drive configuration?

~100mb/s when i transfer file from server to my computer... but only ~50mb/s when i do it from my computer to server......... the funny thing is that sometimes it starts off at full speed which is ~100mb/s but then the speed will drop back to ~50mb/s after like 5 seconds ( sometimes longer )... and sometimes it stays at full speed confused.gif

Use iperf to rule out your network as a possible problem. It will load in memory so you will not be effected by a hard drive bottle neck.

Download:
https://nocweboldcst.ucf.edu/files/iperf.exe

Tutorial
http://openmaniak.com/iperf.php

Run this on the remote machine (server side): C:\>iperf.exe -s -p 9999

Run this on the client side: C:\>iperf.exe -c -p 9999 -P 8 -d

You will get a bidirectional test. The end of the first test will be your download speed. The end of the second test will be your upload speed.

I have gig all the way through, and I can hit over 900 mbits\s
