Hmm, drifting off-topic, but is ionice and/or nice supposed to impact
swap behavior?
My problem is that I can run a program ionice -c 3 nice -n 20 and yet if
it swaps that swapping runs at -10/best-effort, and with ecrypted swap
and swap-on-RAID the loop and md layers also seem to run at high
priority. As a result, a heavily niced process can still kill system
performance, when I'd prefer that it just grind to a halt indefinitely.
It would be nice if all the driver layers pay attention to where the
data they are dealing with came from and prioritize accordingly.
It would be REALLY nice if mysql/etc did the same for queries coming
from niced processes, but perhaps that is too much to ask. :)
And, no, I'm not too cheap to buy more RAM, but I am too cheap to try to
find and buy a replacement motherboard and CPU and RAM that has enough
PCI and drive room for my extra NIC, two tuner cards, 4 IDE drives, 3
SATA drives, and whatever else I have in there... If only I didn't
already have all three memory slots filled (two with 512MB DIMMS on a
slot that could handle 1GB). At this point I'm just putting off the
inevitable and when Gentoo finally moved to KDE 4 I ended up moving to
xfce (which I must say I'm very happy with).
