WampServer 2.5 starts a php-win.exe process on (re-)start.
This process uses a lot of CPU and I/O, causing slowdowns on one of my harddisks and effectively 100% use of one of my CPU cores.
I typically just kill the process manually, which doesn't seem to affect anything in any way.
But I would rather the process didn't start at all, or somehow use less CPU and I/O.
What does the php-win.exe process do and how I can change it?
php-win.exe is the php command line processor but one that does not need a dos box to run in.
It is used by WAMPServer as most of WAMPServer uses PHP to do most of its stuff.
If this initial processing is causing the problems you suggest it is odd as the startup processing done in PHP usually takes milli second.
It would suggest that something is wrong somewhere.
These WAMPServer startup processes do report errors into the PHP error log so I would suggest you look in there for some clues.
