I have a server with SuSE8.1 I have noticed that Linux PCs with old kernel 2.0.x have bad network performance. (92 secs for a PC with 2.0.x against 7 secs for a PC with 2.4.x to copy a 36MB file - same HW) Does anybody have some hints, other than upgrade to newer kernel, since not always possible?
Thanks
I remember seeing some articles and research paper showing horrible 2.0.x kernel network performance especially when they are negotiating with windows hosts. Are the transfers between 2 Linux PC's or 2 Linux PC's with the same HW to a Windows Host. I'm not sure if 2.0.x /proc has the same setup as it does today, but try some parameter tuning in /proc/sys/net/ such as window size, TCPOPTs, etc. etc. There are many how-tos on what some of these ooption do. Maybe the 2.0.x kernel is using some funky or poorly tuned defaults? #------------------------ #Eric Bambach #Eric@CISU.net #------------------------
