i have tried mod_backhand 1.2.1 and when I'm compared
it with standard apache server without mod_backhand
module, I found that this module seems not working
properly.
I have 4 Apache servers with multi-point clustering,
and I tried to send 1000 http request. I made the 1st
server to the most heavy loaded, so I aspect that 1st
server handle the least http request and the other
will handle the last balanced.
but I found that the 1st server handle 270 request,
2nd 230 request, 3rd and 4th 250 request each. why?
my candidation function :byAge, byRandom, byLogWindow,
byLoad.

Load is the system load. That is, by its very nature, a running 5
second average. So, you could assign a million requests to a machine
in one second and not effect the load at all (as many systems only
update the load every 5 seconds).

You might have better luck with byBusyChildren... and try mod_backhand
1.2.2
