I've done another test and you're right. With 5 client IP addresses, there is
load balancing. I've done the test with only 3 different machines which were on
the same network in my previous mail. I would have thought the SH algorithm
could have a "perfect" balancing scheme.
Could the kernel parameter IP_VS_TAB_SIZE influence in that way ? I've put 16
bits instead of the default 12.
Thanks very much for the time.
