PHP Accelerators
eAccelerator
Submitted by chris on January 15, 2006 - 17:29We have been using this PHP accelerator (0.9.X), on multiple servers, for a long time. It's used on some high traffic sites without any problem.
Install:
a) Download a copy of eAccelerator that is compatible with your version
of PHP.
This can be an issue with eAccelerator. Sometimes it can take a
little time before the Windows binaries are available for the most recent version of PHP.

Xcache a new PHP accelerator ? (updated version 1.0.2)
Submitted by chris on August 16, 2006 - 11:43It looks like the author of Xcache grew frustrated with the current offering of PHP accelerators and decided to build a simple stable PHP accelerator. For example, eAccelerator works perfectly on multiple servers here but on others it crashes multiple times a day. I'm still investigating this: eAccelerator crash
Alternative PHP Cache ( APC )
Submitted by chris on January 15, 2006 - 17:51This 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.

Running Apache + PHP + Accelerators under Windows 2003
Submitted by chris on September 19, 2006 - 20:54I have been getting some instability running Apache with PHP + Accelerators under Windows 2003. I will log my finds in this article. Visit regularly for updates. I ended up running 7 Apaches on a Windows 2003 Server to test all different kinds of configurations. Recently because it was becoming complex, I started logging my finds. This page is probably for the hardcore debugging type...
Mitigating factors:
- Most crash seem to happen because of load (with very low traffic you might
never experience problems).
- My PHP applications are very demanding. Especially Gallery2 which relies on
external libraries for processing images. Again other PHP applications might not
experience these problems.
-If you have issues with IIS, these finding might also be applicable.
eAccelerator crash
Submitted by chris on August 16, 2006 - 09:32eAccelerator crash (Updated)
I've created an article to try to track what works and what doesn't: Running Apache + PHP + Accelerators under Windows 2003
After moving a site with some traffic to an Apache 2.2.x server, I have been getting multiple Apache crash per day. Before I was only getting these about once a week. Here is what the error looks like in the Apache error.log:
Zend Optimizer 2.6.2
Submitted by chris on January 13, 2006 - 15:34I prefer a manual installation (it easier to upgrade in the future). This generally holds true with most Open Source software on Windows.
1) Download the free Zend Optimizer.
eAccelerator problem with PHP: Crash under Apache
Submitted by chris on May 22, 2006 - 22:06Once in a while under Apache 2.0.55 or 2.2.2, I
would get a crash with a line like the following in the log:
[7508] EACCELERATOR: PHP crashed on opline 48 of preg_replace() at
G:\DomZeus\sitebuddycom\wwwroot\modules\search.module:354
This mostly likely an eAccelerator bug (not 100% sure).
Meanwhile here is a solution to try to avoid it. Since in my case the error
happens regularly (once a day?) with the file search.module, I decided to tell
eAccelerator to stop trying to cache that file with:

APC problem with Gallery 2
Submitted by chris on May 22, 2006 - 22:16Under Apache 2.2.2 and 2.0.55 using APC (3.0.11-dev) I could not delete an image using Gallery2.
My temporary solution is to disable caching of Gallery2 classes in APC with:
apc.filters="-g2.*\.class"
