#9628: Really bad disk performance / cache behaviour

------------------------+------------------------------
I've started using Haiku lately (to develop BeScreenCapture), and I found
it really bad regarding disk read/write performance. Actually it could be
a problem of cache behaviour.
This is what happens: when I open a small file with PE, it takes some time
to open, and during that time, the disk spins like crazy. Same thing when
I save the file.
Moreover, sometimes the disk spins like crazy also when I open the deskbar
menu, or when I click "Start Capture" in BeScreenCapture (an operation
which does not involve the disk at all, or in minimum part, at least).
Note that the same machine (Intel T5550 processor, 4GB RAM) runs Ubuntu
12.04 just fine.
The Haiku partition is 4GB, swap is around 200MB (but I tried with 1GB of
swap as well).
Note that lately (but could be two years, actually), Haiku on VirtualBox
or qemu is practically unusable on this very machine, while I remember it
used to be much better.
