If your employer is serious about server performance then they should buy you a bunch of systems for testing such things.
That'd be nice. But that costs, and they may not have the budget. At VLSCI we're lucky enough to have a spare box for QA, but that's not a compute node clone, it's an infrastructure box clone.
You shouldn't need a box of the same specs as production systems. But hypothetically speaking even if you did need one with the same specs any reasonable cost-benefit analysis would justify it. If you have 100 production systems then the 1 test system only needs to deliver a 1% performance benefit in production to pay for itself. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
