RE: too many page faults

Okay.....

So to reduce the cache size do I need to change the cache_swap_low to an
even lower amount and then change the cache directory size or what??

The problem is not the size of cache_mem (24M is rather big for a 128M
system)
but the size of your cache.. For every object in your cache, a certain
amount
of RAM is used (I'm not sure, but I thouht 64-byte for every object)..

So the solution might be to get more RAM (e.g. 512-MByte) or to reduce the
size of your cache..
