What happens if you take NFS out of the equation? Try creating a local
user on the K12LTSP server and give her a non-NFS home directory. How
do the slow apps respond then? Then create a Samba/LDAP user but give
her a local home directory (e.g., "/tmp/username") and see how the
apps respond.

I'm guessing that you've got NFS locking issues. Every time I've seen
behavior like this that seemed to be the culprit, but an update
has always fixed the problem before I got time to track it down
further and figure out *why* locking was a problem.
