[Bug 564504] [NEW] kcryptd not multithreaded?

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Binary package hint: plymouth

When copy/moving a large file from an encrypted volume -while logged in
on an encrypted home- on my I7 with SATA-300 disk, my 9.10 64-bit
desktop slows down considerably.

I noticed I have 4 crypto processes running.

When I move/copy the file while logged in on an unencrypted home the
desktop is still usable.

It looks like Gnome waits for requests somehow, but is unable to
complete until the copy/move ends.

I have the feeling the kcryptd process is handling one request at a
time, and is not multithreaded.

Any ideas?

ubuntu 9.10 amd64
cryptsetup  2:1.0.6+20090405.svn49-1ubuntu7.2
