[Bug 82528] Re: Write load on DM-Crypt LUKS partition (reiserfs and ext3) jams system

[slarti]

I still have this issue. When copying large amounts of data (rsync a
directory tree with small and big files) to a luks/dm_crypt encrypted
partition, the system freezes every 2-5 seconds for 2+ seconds.  My
system is a Core 2 Duo E8400 with 4 GB RAM and runs runs on Ubuntu 8.10
x64 (Intrepid) with the current standard kernel 2.6.27-11-generic #1 SMP
Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux. Renicing kjournald from
-5 to 0 attenuates the situation a little bit -> keyboard input is more
responsive, but switching between applications (or for example tabs in
firefox) is still painfully slow.
