Re: PATCH: vm/kswapd in linux-2.4.0-test2

Hello Andi,

Thanks for trying this patch....but I still believe it needs some tunings.
I will be really interested to get some stats. Could you send me the
report logged by Alt-SysReq-M after some [normal] swap utilization ?
Also, adding your cpu and hard drive type would help a lot (this way
I can have an idea about the ratio between the memory/cpu access
and the I/O throughput).

Since I'm asking for something, I believe it's fair to do the same.
Here is what I got after a working day using this patch.

CPU: AMD k6 3D 550Mhz (1097 bogomips)
HD:   IDE WDC ATA66

SysRq: Show Memory
