As of 2.1.120-1 linux passes some severe beating on the NFS client and networking code! The netscape-empty-trashfolder-on-nfs-home-test has been run 6 times with success. This test always crashed in 2.1.119!
These operations were done at the same time in a final stress test:
o compile kernel on nfs-mounted partition o run empty-trashfolder-test on nfs-mounted partition o run 'rsh remote-machine "cat /dev/zero" > /dev/null' o run a program that continuously touches 100 Mb of heap (the machine has 128 Mb dram) o ktop running in fast update mode over X-windows o serving a rebooting linux nfs client (running 2.1.120-1 SMP)
No file corruption was detected ('diff --recursive -d ...' was used).
During the test the machine was operated remotely through X-windows. (Doing some www-browsing of text intensive pages and some system monitor in a subshell under Xemacs.)
The network connection is a 3c905 to a 100 Mb/s Full Duplex 3COM switch. During an uptime of approx. 4.5 hours the machine sent 65 million packets over eth0. The 3c59x F upgrade in 2.1.120-1 was backed out to get any network contact at all.
