Hi all,

somewhere in the 2.4.21-xx series (currently running -rc1 here) seems
to be a VM regression, that results in quite hefty swap-outs. The box
is an Athlon-XP with 512MB RAM, running batched gcc jobs (distribution
builds taking three days and more...). But the box is used a normal
workstation, too. My normal desktop programs constantly need to get
swapped-in - quite annoying. This only start to happen after an uptime
of a day.

So the CPU:

vendor_id       : AuthenticAMD
cpu family      : 6
model           : 6
model name      : AMD Athlon(tm) 4 Processor
stepping        : 2
cpu MHz         : 1460.481
cache size      : 256 KB
