With some help :-) i could manage to share almost all system files (/, /usr,..) through NFS. i can see a reading speed difference 4 time slower on client than on server (time tar -cf - /usr > /dev/null). I will play with jumbo MTU for network performance, but would anybody know if i can ask system files NFS exports to stay in server memory ? I have less than 2Go to share and 2GO DDR2 is affordable. Thanks a lot, Best regards,
