Things to try:
- Be sure you're using rsync 3.x, as it has a better hash algorithm for
the large numbers of checksum
I really don't think it's a good idea to sync large data files in use,
which is modified frequently, e.g. SQL database, VMware image file.
As rsync do NOT have the algorithm to keep those frequently modified
data file sync with the source file. And this will course data file
corrupted.

the speed is reasonable, but i guess it`s not the optimum - at least i

That's vague and subjective, so
files, how can i calculate the risk
of 2 files being NOT perfectly in sync after rsync run ? i assume there IS a
risk, just as like there is a risk that 2 files may have the same md5 checksum
by chance

I don't see how you came up with such numbers.
If files change completely then I don't see why
you would transfer more (or less) over the network.
The difference that I'm thinking of is

Hello,
i`m using rsync to sync large virtual machine files from one esx server to

rsync is running inside the so called esx console which is basically a
specially crafted linux vm with some restrictions.

One way I've been trying to speedup rsync may
not apply in every situation. In my situation
when files change, they usually change completely.
This is especially true for large files. So,
the rsync algorithm does me no good. So,
I've been using the W flag (e.g. rsync -avzW)
to turn this off.
