> I have updatd my pathset with latest bits for 2.4.18-rc3.
I'm looking forward to trying your patchsets more in the
future. I was consolidating some results and it made
sense to include 2.4.18-rc2-jam1.
2.4.18-rc2-jam1 was the only kernel of these three that had Andrew
Morton's read_latency2 patch. 2.4.18-rc2-jam1 was compiled with
vm-24, vm_io-2, sched-O1-K3, sched-aa-fixes, lowlatency-mini,
read-latency2, and sched-balance applied.
Tiobench read/write latency is where the biggest differences are.
K6-2 475 mhz, 384 MB ram, IDE disks.
