Still might not present a solution (short of unsubscribing much data) but I'm mindful of the oddity that disabling automatic send/receive makes such a difference.

Actually disabling Send/recieve didn't do anything :-(

I held a stopwatch to it for both pre and post and no difference.

T-Bird transfers get 1 min. 35 secs for 1600 messages.

Outlook gets 3 min. 6 secs for the same amount of messages.
