When I last moved my own email from a small but well-run ISP, I did see 
3.8MB/sec from them, but Fastmail topped out at just 872KB/sec (but 
didn't stay there).  This was done from where I work, and have an OC-3 
(about 18MB/sec) connection on Level 3's network (one of Fastmail's 
peers).  I'd guess that Fastmail, more so Google mail, are fairly 
heavily loaded.

It's been a while since I last used it, but I haven't had any any 
trouble with the precompiled Darwin version.  A typical command line (my 
needs are simple, heh) -

./imapsync_bin_Darwin --host1 Skipper.Opus1.COM --user1 billy at MIX.ORG 
--password1 MASKED --ssl1 --host2 mail.messagingengine.com --user2 
billy at MIX.ORG --password2 MASKED --ssl2 --tmpdir /var/tmp

And the results -

     Total bytes transferred   : 3383047221 (3.151 GiB)
     Average bandwidth rate    : 225.2 KiB/s
     Memory consumption        : 2737.7 MiB
