Yes, it is. In jaunty, the current warm start (everything in cache,
ie. login, logout and then login again) time is ca. 5 seconds, with
compiz, something that would be actually ok for a login time in
general instead of the current status.

And the I/O problem comes from the hundreds/thousands of small files
that are inefficiently read. The amount of transferred data is not
that much that it would take more than 2-4s to read on modern even
laptop hard drives, if the data would be sequentially available in a
one big chunk.

This has been fixed in the newer libcompizconfig in jaunty.
