2.2.14 works fine, although I think that 2.2 series in general seems to
have braindead paging behavior. To be precise: I think that some form of
"maximal/minimal buffer size" option seems to be in order soon, as (back at
my previous company) I had machine with "only" 128MB of RAM, and I
regularly used only 60-90MB of it, and it still swapped like hell under 2.2
series in general and 2.2.14 in particular, whenever I did something
disk-heavy such as "cvs update". It raped the performance, so I wound up
turning swapfile off. No more problems.
In my next place of employment, I needed bit more bloated apps so I got
192MB of RAM, turned swap off, and even 2.2.15 works fine for me
:-P
