Rsync 3.0.0 report and a performance question.

Hi,
first a short success report: rsync 3.0.0 works as far as I can tell
flawless for me.
My performance question: Below are of some recent backup stats one,
using the old protocol (29), the other the latest cvs (30). As you see,
the file creation time has dropped significantly (0.01 sec vs 80.2 sec).
Still the overall performance hasn't increased much. This may not be
surprising as very few data (42 and 11 files) are actually transferred.
Anyway, I am wondering why it is taking full 12 minutes to complete the
rsync. The connection link is a GigE LAN. Thus most time is spent
comparing the file lists at sender and receiver. However, a comparison
rate of 217293 files / 670 sec = 325 files/sec seems pretty low, no?
Regards,
Matt
