I went ahead and rolled out the 1000Mb network this weekend. Came up with a procedure to attempt to benchmark the file copy performance between my two main machines before and after the roll out. I basically used both ftp and samba mounts to transfer files between the two machines on my net. Got a puzzling anomaly with the benchmark stats.
It looks like a samba file copy (RH 9 box -> WinXP SP2) is way slower on the 1000Mb than it was on the 100Mb (the 100Mb looks to be about 1.5 times faster than the 1000Mb), everything else is about what I expected (~2 to 3 times faster, with ftp being significantly faster than samba). I reran the benchmark and got basically the same results so I did a few copies by hand and got roughly the same as the benchmark. Anyone know what could cause this? I'm thinking maybe an old version of samba (I think it's at 3.0.5 and the one on the box is only at 2.2.8a)... The RH box is about to be wiped and Woody put on it, I'll rerun the benchmark afterwards and see if the anomaly is still there. Here's a link to the benchmark procedure and the last set of results http://www.kuhns-la.com:9080/netbenchmark.html - notice the PULL stats in the "Results: SAMBA File Copy Throughput in MB/s" section, averaged 5.774 MB/s on 100Mb and only 3.868 MB/s on 1000Mb. ?????? Sorry for the messy html - I was using Excel to compute the stats so I just exported it from Excel as html. If anyone wants the benchmark scripts let me know. James
