Wow, never would’ve guessed this.

Never would have guessed that on-disk temporary tables are that bad for performance. Peter over at the MySQL Performance Blog shows otherwise.

mod_security and Drupal 6.2 issues.

If you’re going to be using Drupal with mod_security, making the following changes will probably save you some frustration later :).

<LocationMatch “/”>
SecRuleRemoveById 960010
SecRuleRemoveById 960015
SecRuleRemoveById 960032
SecRuleRemoveById 950107
</LocationMatch>

Also, set SecResponseBodyLimit and SecRequestBodyInMemoryLimit to something like 51200000 and 12288000 respectively. They may seem a bit high, but if you’re managing a lot of Drupal users and permissions I’ve run into problems with them.

Happy Drupal-ing.

Firefox 3: The Next Generation

Don’t get me wrong, I love the Firefox web browser. It’s the greatest thing since tacos. But Firefox 2 has some of the worst performance problems I have ever seen! On Linux, if I leave one tab open with a flash movie playing, the Firefox process will eventually grow to enormous proportions. Yes, I know this seems like a Flash plugin problem, and it very well may be. But I do know that if I open the same page with Firefox 3b5, the memory usage stays constant the entire time.
