I did almost the same test and found the following values in MByte/s: FBSD 5.2 -> 5.2 / 4,6 (Client 1,1G Cel, Server C3 800) Linux -> 5.2 / lockup (Client 733 PIII, Server C3 800) FBSD 4.9 -> 5.2 / 2,8 (CLient 233MMX, Server C3 800) FBSD 5.2 -> 5.1 / 6,5 (Client 1,1G Cel, Server C3 800) Linux -> 5.1 / 9,8 (Client 733 PIII, Server C3 800) FBSD 5.2 -> 4.9 / 5,8 (Client 1,1G Cel, Server C3 800) Linux -> 4.9 / 9,8 (Client 733 PIII, Server C3 800) FBSD 4.9 -> 4.9 / 3,0 (Client 233MMX, Server C3 800) DragonFlyBSD as Server resulted in about 5% more performance than 4.9 (linear exept Linux Client as it performs with the maximum Ethernet Speed) My tests were without modifying any rsize/wsize. But even with (rw)size 32k i had expected to be able to transfer about 9 MByte/s from a 233MMX box. 3MByte/s is absolutely lousy. What hardware do we need for just tranfsering bytes? 1GHz? I think 233 MHz with 64MB for OS should be more than enough. Regrettably I haven't had time to install a Linux on the 233 box. Btw. Linux = DebWoody (2.4.22) and all clients have fxp interfaces! Summary: 5.1 as server was a lot faster than 5.2 as server so is 4.9. Fastest was DragonFlyBSD but anyhow, just Linux as Client does a reasonable job. And not to forget the broken Linux -> 5.2 support!!! -Harry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQBAG+39Bylq0S4AzzwRAo7WAJ97RNaPuxrh3f1W/XxzfoLr/J6EEACfZupI phXfXyeRPhHE/Y8yRpdYJjc= =RkHr -----END PGP SIGNATURE-----
