(I don't mean the T2's chip, I mean the software) -- if so, disable it, deregister it, uninstall it and purge it because it will kill performance. > I noticed this as we are using an external monitoring system > (Gomez.com) and we started seeing these wildly varying times for > transaction processing. > > I have tried a cut down SSL setup for testing, and examined every Does that mean you tested the same setup in plain-text?
