I hope someone can help me out here as I feel like I've hit a dead end. I've tried several set ups of Apache (32/64 versions and 2.2/2.4 versions) using mod_fcgid (relevant version for Apache) and PHP nts 5.3.14.
This works fine on one server (Windows 2008 R2 64 bit), I fire off a ton of requests and see php-cgi.exe processes being spawned to cope with them. However, if I take a copy of this setup to two other servers (same OS) and run it without any config changes, it only spawns a single php-cgi.exe process to cope with all the requests.
Really don't know what's going on anymore, anyone else run into this? I don't think it's a configuration issue, as the same config runs fine on my local machine and another server. |

| Are the number of requests are the same? Run as the same user? |

Same number of requests and I tried firing off the requests as different users just to be sure, no difference. I'm using the ApacheBench tool.
Starting to think it might be an Operating System problem with this setup, as I installed IIS and PHP (using their Web Platform installer thingy) via FastCGI. It performs much worse, seems to start multiple PHP processes but doesn't use them or is slow to communicate with them as it's 10 times worse for reqs/s. |

| Just to update on this post of mine. The server was a VM with only a single CPU provided to it. When this was increased to 2, the problem with no extra PHP processes being created, disappeared. |
