[wp-hackers] Quantity of Queries - Performance

[Joost de Valk]

Hey,

I've been playing with this plugin a bit, and submitted a patch to Frank 
who was kind enough to immediately commit it, based on my experiences 
I've written a post on it: 
http://yoast.com/wordpress-performance-optimization/

There's one paragraph in there that everyone should take note of about 
empty options, in short:

     doing a get_option to check whether a certain option is set or not, 
is actually more expensive,
     database wise, than just setting the option and leaving it empty, 
as it causes a query...

Might be good to know for the plugin authors out there!

Best,
Joost
