Hi,all

You might remember I had issues with massive swapping and wanted to know
whether I can control the amount of cache and buffers and so on.Well I
thought a mem upgrade would do the trick ,but no :-(
Not easy to explain to my boss that it still crawls with 512 MB mem and
that's the max limit in this laptop..Anyone found any solutions ?? Check
this out:

it just caches like crazy and things start to crawl cause its
swapping.More than 300 MB of cache what on earth is being cached ?? I
can't stand ths anymore I guess I'll have to back down to 2.2 again,but
that'll have other downsides :-( *sigh*
I'm willing to help as much as I can with this I don't want to give up
on Linux just like that.

best regards

Christian
