I probably have way too many emails and folders and sub-folders and virtual (saved search) folders for 32 bit TB hence my many year problems with it "not responding" for LONG intervals. TB files have been moved to private flash drive years ago and server is CGP also running on same machine and its files are also on their OWN Flash drive. I'm using IMAP, of course. And TB is also for various other accounts not not running on my server. 64 bit CGP runs as a server, of course, and is NOT a bottleneck, but 32 bit TB I believe IS, though perhaps I've got sub-optimal settings somewhere or even just too many emails in many of the vast number of folders. And it just now crashed yet again while I was about to try watching "page fault delta" after starting a "compact all folders" which I had yet to do.. I have prayed for years for a 64 bit version built by the same team behind the 32 bit version I am stuck with, and HOPE that will help. My CPU never seems to be MAXed when I'm stuck waiting for TB to let me continue. Is there something I might have missed? FWIW, this is on a W7 Ultimate with a getting old Quad Core I7 920 1366 socket maxed with 24GB dram. Paging space is way oversized fixed space on two fast hard drives and isn't fragmented, so no problem there. When can we get a 64bit proper version of TB? Every day there are probably fewer 32 bit machines running TB.
