I'll have to change the network around to be able to do this, perhaps over
the weekend.
In the meanwhile, your words made me think of something else, I was certain
the delivered content was the same in every case, but the page is somewhat
large, around 110KB, so I repeated the tests with a tiny html page (80
bytes) and a tiny php (same 80 bytes but also connecting to a MySQL DB)
page; the same setup that serves 6000 large pages per *minute*, now serves
20000 tiny html pages per *second*, or 4500 tiny php pages per *second*.
The limiting factor seems to be, after all, the actual bandwidth. Part of
the network plumbing that I took for all-gigabit must be 100mbps.
LVS rocks, and I failed :)
Thanks for your help!
Paulo Rodrigues
