We have run 2.4.10 under a heavy nfs load and kswapd now appears to be under control ( never went above 88.5%cpu and then only for a short time), but the nfs performance is about 45% of what it had been for the 2.4.5pre1 kernel. The response time grows steadily throughout the test until the test goes invalid.
Hardware: 4 processors, 4GB ram 45 fibre channel drives, set up in hardware RAID 0/1 2 direct Gigabit Ethernet connections between SPEC SFS prime client and system under test reiserfs all NFS filesystems exported with sync,no_wdelay to insure O_SYNC writes to storage NFS v3 UDP
I can provide top logs if anyone would like to see what is happening at any particular time. Also, if you would like to see some results from a particular test, please let me know what test it would be.
We tried the 00_vmtweaks patch from Andrea and it failed to boot. There was an issue starting kswapd and the kernel would oops.
