Given your following comments, you may not have to - but it will give you a decent baseline for "idealised" operation. Unfortunately, once you have remote clients accessing a system then you have all the variations they can throw at you - PMTU problems, non-deterministic latency changes, TCP window scaling... etc etc. The list can grow very long, and tiresome! If you figure out that you can handle (say) 1000 page views/second in tests, you might find that in a "real" operating environment you manage to achieve 25% of that. At least, if you do, you'll know you are doing well! Remember also that static tests of the type you did don't exactly stress the system as it can deliver a lot of data from the kernel's filesystem cache (in memory) rather than reading from disk. If you can do so, modify your PHP to do some sort of calculation or fetch some data in a random fashion from your database (as MySQL will also cache repeated requests if configured appropriately). Not that any of that is LVS related, of course; it's just good practice when establishing a baseline for your system :) Glad we've helped so far!
