Hi Martin,

Your problem seems interesting...

Maybe because your users are on a high speed LAN than mine
which is mostly on low speed PPP serial line. You got pretty
impressive hardware too. :)

I would suggest...

> cache_swap 15000

> cache_swap_high 90 <--- tune this parameter
> cache_mem_low 75
> cache_mem_high 95 <--- tune this parameter too

When your cache swap reaches 90% (cache_swap_high),
it will start to trash your disk. At the rate of the
growth of the swap area, you need probably need to
reduce the "cache_swap_high" such that Cached can
start clearing up the disk eariler and such that
the growth rate of swap area will not be able to
catch up.
