I've been doing some tests recently here at work on our gigabit network and I've noticed something peculiar. When I do large file transfers between servers, I noticed that I don't get anywhere near what I should be getting for a gigabit network. Heck, I don't even maximize a 100 baseT network either. Out of all the file transfer tests, the fastest I was able to get was 91Mbits/s on a gigabit switch. We've come to the conclusion that the hard drive was the bottleneck. Once the initial burst from data in the cache runs out, it seems the transfer speed slows to what the hard drive can sustain. Keep in mind we're using SCSI RAID drives here. I find all this rather strange since the hard drive manufacturers have advertised speeds much faster than what I'm getting. I remember the ultra DMA speeds were like 66MBytes/s, which would still be much faster than what I'm getting. What gives? Am I missing something here? I tested this out on my home computer going from SATA to SATA hard drive... and the results weren't much different. Any input/ideas/consiracy theories would be much appreciated. Thanks!
