#56 mount -t squashfs very slow

[Massimo B.]

Hi,

I'm using 3.14.4-ck from sys-kernel/ck-sources on Gentoo. I also use squashmount which itself mounts some squashfs.
Recently the mounts are very slow, every mount takes more than 30 sec. Also other users have reported this.

The mount command is like this:
/bin/mount -t squashfs -o loop,ro,noatime -- /opt/Adobe.mount/Adobe.sfs /opt/Adobe.mount/readonly

I can't see any other debug logs than this when loading the squashfs module:
Aug 26 15:26:34 [kernel] squashfs: version 4.0 (2009/01/31) Phillip Lougher
