Performance Help - Network based DATA drive slows client

Our setup:EXE - C:\Program Files\Lotus\Notes\notes.exe

DATA - P:\Lotus\Notes\Data (network drive)

INI - P:\Windows\notes.ini

I use a custom launch icon ( =p:\windows\notes.ini ) to start notes.

Currently I have ~10 user in UAT for the 8.02 standard client. I’ve found an issue that can be reproduced throughout the group.

If a user selects more than one email from the inbox to delete, it takes 3-5 seconds to refresh the view.

I’ve had both the netowrk and server team investigate the network and the disk I/O - NO RESULTS.

As a test I’ve moved the CACHE.NDK file on to the local disk. NO RESULTS.

I’ve then moved the entire DATA directory to the C:\Program Files\Lotus\Notes\DATA - AND IT WORKS. Performance is now MUCH better.

So my question is can you think of anything I can change apart from CACHE that would enable me to keep the DATA directory on a network drive?

Thanks.
