Filr Speed?

Hi all,
I'm running the release version of Filr across 3x VMs (Filr, Search, MySQL). They are each installed on fast SAS drives, in an ESX farm with heaps of capacity.
When I access Filr using the browser, I see my home drive and a Net Folder I have set up. When I click on my Home drive, it takes approx 14 seconds for the root folder list to appear. The Net Folder (which has Just-in-time enabled) takes about 8 seconds.
The actual file server is an OES11SP1 VM in the same stack, and it's speed is fine when I access it across NCP or even NetStorage.

If I go from the Net Folder back to the Hom folder, it still takes the same time to bring up the top folder list of Home. SubFolders seem to be more responsive?

I really am not sure where to start, or if this is normal or not?

Can anyone comment on their speed?

thanks.
