PHP 4.1 and quicker run times

The php readme / changelog noted that they worked with m$ and have made great improvements in the speed of php on windows. Now I find this to be a very generic explanation and not very helpful. Does this mean: a) Its efficiency and speed was improved on running on WINDOWS? OR b) Its efficiency and speed was improved on running on IIS? To often (especially when dealing directly with m$), IIS means windows. People tend to forget there are plenty of win32 apache ppl running php. (If you don't believe, try finding documentation on php/apache win32. There is next to none. Its all *nix / apache or windows / IIS). So my question comes down to: Was the speed greatly increased on my win32 apache server (as implied since great improvements were made on WINDOWS (didn't mention IIS) OR does once again windows mean IIS? Hopefully i can get a definitive answer on this and not speculation :). Cheers, Peter __________________________________________________ Do You Yahoo!? Check out Yahoo! Shopping and Yahoo!
