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!
