I have to correct my previous mail.
I am experiencing since some time a substantial slowdown on my XFS file
systems (could also be related to upgrading to kernel 2.6.32). This slowdown is
also quite perceivable on system upgrades with apt-get/aptitude. Now for the
first time Bug#605009 came to my knowledge and I guessed it could also be a
cause for the meanwhile rather painful upgrades on my desktop machine.
I just upgraded my testing machine to dpkg 1.15.8.6. and tested with
'aptitude -o DPkg::options::="--force-unsafe-io"' and see that my guess
was at least partly wrong. Unpacking of the debs still causes very heavy load
on the harddisk while final install seems to be faster.
So the problems I am facing with XFS are probably at least not closely related
to #605009.
Sorry for the noise,
