The files are very similar, a maximum of about 5GB of data differences over 80GB. The CPU on both sides is low (3-5 percent) and the memory usage is low (11MB on the client, not sure on the server).
Full rsync options are: -ruvvvvityz --partial --partial-dir=.rsync-partial --links --ignore-case --preallocate --ignore-errors --stats --del --block-size=1149728 -I I'm using the -I option to force a full sync since date/time changes on database files is not a reliable measure of changes. I'll try the block-size at 1638400 although I have not seen a big change in moving it from about 287000 (default square root) to 1149728.
