We're running along smoothly with triple our typical heavy load (1000 users currently).  mySQL peaked at 106 queries/second, and I still have CPU and memory to spare.  Talk about a relief...

  Re: IIS 6 + PHP Performance Issues Reply Contact That's great, glad it worked out for you! Your hardware configuration is an great example of where creating a web garden can really help push performance along. Unfortunately my server only has the one CPU so there is no advantage from increasing the worker process count (probably would even slow things down). ---------------- Dominic Ryan Microsoft IIS MVP www.iis-aid.com My IIS articles My PHP articles My How-to guides

Also something about PHP sessions can't transfer between gardens properly? Have you experienced and problems running your sites app pool in a web garden?

  Re: IIS 6 + PHP Performance Issues Reply Contact I'd be interested in reading that if you were able to locate the source, however I've never had any issues using PHP ISAPI on IIS6 in a web garden. It is definately not a set and forget kind of option as there are some very real risks. The only memory issues I've found you really need to be concious of is that your PHP memory consumption will increase by a factor of x, where x is the number of processes running in your web garden. For example if PHP is topping out at 128MB of ram on your server, and you configure IIS to use a web garden with 4 worker processes then your memory consumption will now top out at around 512MB. This potentially could comsume all of your physical memory which would result in the use of virtual memory and page file thrashing.   ---------------- Dominic Ryan Microsoft IIS MVP www.iis-aid.com My IIS articles My PHP articles My How-to guides
