BENCHMARKING (was: [mapserver-users] professional MapServer services list? / ArcIMS-MapServer choice)

[Zak James]

There is also a free package for windows called phpedit 
(www.phpedit.com) which puts a friendly GUI on the php debugger. It 
makes remote debugging setup easier, too. It's a little rough as an 
editor, but the debugging support is solid.
