Re: [Evolution] Slow filtering under NFS

["Jonathan F. Dill" <dill umbi umd edu>]

What Linux kernels are involved?  Are all of the Linux updates applied? 
Have you tried fs benchmark like "bonnie" to see how fs access to the
NFS server is in general independent of evolution?

My bet is it's an OS/kernel issue and not an evolution issue, possibly
to do with file locking and/or blocking I/O.  Why not just use plain
IMAP to get to the stuff on the server?  File locking with e-mail is a
very messy business, I think it's best to leave it to IMAP which knows
how to handle it properly vs. complicating issues with NFS, I just don't
get what the advantage is.  See the pine docs for more info about file
locking issues with e-mail.
