I'm afraid I have no idea on this. I reviewed the relevant changes as
near as I could figure them out, and I don't see anything that should make
history writes any slower. The main change in this area is to avoid
fseeko and ftello to move around the history file since they do a flush
and instead use an internally maintained offset, but this should actually
speed things up and make fewer system calls. The code was also modified
to actually *do* something for dbzsync, but history sync isn't a
substantial component of your timings either before or afterwards.
