Apache Rotatelogs.exe for Windows Server

When using the Apache tool, rotatelogs.exe, you can see (using the task manager) multiple instances of rotatelogs.exe. Even when using it on just 1 web site!
To make this issue even more disastrous when restarting the Apache (httpd.exe), not all instances of rotatelog.exe are released.
Doing some research on the web it looks like this issue has been going on since years (Apache 1.3, 2.0 and now 2.2....).
Note: I've verified this issue with both Apache 2.0.55 and 2.2.0

Alternative PHP Cache ( APC )

This accelerator does not perform well at all under Apache 2.2.0. Just running one of my site used nearly all the memory (30M max).
The segment feature doesn't really work on Windows, so you're limited to 30M.
Update02/2006: Under Apache 2.0.55 and 2.2.2 it seems to perform normally.

eAccelerator seems faster then APC. But if you are running multiple instances of Apache on the same server you will appreciate a second caching tool for PHP. I use both APC and eAccelerator with production sites. APC seems to be getting better just in the last 3 months (since 01/2006).

Note: This accelerator might get better, in the near future, since some of the PHP developers appear to also be involved with APC.

Install PHP in CGI mode on Apache 2.x

Running PHP in CGI mode on Apache 2.x

I was running PHP as a module under Apache and decided to try the cgi mode. The instruction all over the web are pretty simple.
Add the following to your httpd.conf:

ScriptAlias /php52/ "E:/A22/php520/"
SetEnv PHPRC "E:/A22/php520/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php52/php-cgi.exe"

The SetEnv line is useful to indicate were to look for your php.ini first.

Upgrade Gallery 2.0 to Gallery 2.1.1

Reference: http://codex.gallery2.org/index.php/Gallery2:faq#How_to_upgrade_Gallery2.3F

This is exactly what I did and went perfectly well.

1) Backup MySQL DB and g2 data directory and current G2 app files.

2) Download full install unzip over existing. Keep the existing config.php in place, this should not be an issue since a new install should not contain one)

3) Disabled the current gallery module from within Drupal
