So while we're here, an idea someone proposed in #debian while discussion this
thread (email@example.com, you know who you are): QoS for application paging
on desktops. Basically you designate to the kernel which applications you want
to give priviledges, and it avoids swapping them out, even if they've been idle
for a long time. You designate your desktop apps, and then when updatedb comes
along they don't get kicked (but something more intensive like a kernel compile
would claim the pages). Maybe it would be as simple as a category of apps whose
pages won't get kicked before a singly-touched page (like and updatedb or
streaming media run).
For the record, I'm impressed with the new VM design, and I think its unbiased
behaviour (once the bugs are ironed out) will be exactly what I'm looking for
in life (traditional Unix "the fair way") :) Currently using a 4-way RS/6000
running AIX 4.2 which has been up for a long time and is running a lot of
programs (even though the active set is quite reasonable), and decides to swap
at evil times :)
Looking forward to the tweaks/settings options that will appear on this VM over
the next little while...
