[coLinux-users] NFS performance and colinux

[Claude L. (QB/EMC) <cla...@er...>]

Hi,

I am currently trying to build a Solaris jumpstart server using =
colinux. This Linux based jumpstart version already works fine in =
native Linux solutions. The Solaris jumpstart service requires RARP, =
bootparamd, TFTP and NFS services. All those services behave perfectly =
under colinux but the NFS service exhibits an important performance =
problem. The NFS service seems to be a way too slow compared to the =
native solution. The other services run at a very acceptable =
performance. It is diificult for me to measure this problem but using =
the native solution, NFS roughly speeds up at 1000 to 1500 =
packets/second (maybe more) while colinux show a maximum of 10 =
packets/second.

I am using colinux 0.6.1 over kernel 2.4.26. The original distribution =
does not offer the NFS kernel side server. So, I have recompiled the =
vanilla 2.4.26 kernel with the required options to run nfsd from =
colinux. I have simply updated the modules in my Fedora Core 1 =
"virtual" machine and I got the NFS service working fine. I am using =
Windows 2000 SP4 and bridged networking.

If somebody has an idea why the NFS service is so slow, please, do not =
hesitate to contact me.
