The only significant overhead of shared folders is the synchronization that
occurs when a shared folder is opened. Otherwise the only overhead of a
shared folder is an extra symlink that must be followed each time a message
is read.
Exactly. The speed difference on "open" operation is the thing I
mentioned. Is there a way to make the synchronization a background
process? Just run one more thread (per shared folder?) to ensure the
consistency. Synchronization of 2000 messages really takes 5-10s on
PIII-800.
