Yeah, but this is what it actually says:<p><i>If you need to run your production system on Windows then IIS7 will give you the most stable and best performance.</i><p>So it seems to be recommending IIS7 specifically, IIS 7.5, IIS 8 and IIS 8.5 have come out since then. So it is a bit like saying you should run this software on windows vista for best performance. IIS7 is old software.<p>I guess I&#x27;m asking, have the IIS team given up on PHP performance or is this recommendation really out of date.
