Questions about it:
Q) Does swap-prefetch help with this?
A) [From all reports I've seen (*)]
Yes, it does.
No it does not. If updatedb filled memory to the point of causing
swapping (which noone is reproducing anyway) it HAS FILLED MEMORY and
swap-prefetch hasn't any memory to prefetch into -- updatedb itself
doesn't use any significant memory.
however there are other programs which are known to take up significant
amounts of memory and will cause the issue being described (openoffice
for example)
please don't get hung up on the text 'updatedb' and accept that there
are programs that do run intermittently and do use a significant amount
of ram and then free it.
Different issue. One that's worth pursueing perhaps, but a different issue
from the VFS caches issue that people have been trying to track down.
