    Hi , The CPU usage for wordpress is high all the time and i have this problem with all hosting companies that i run my website on . Is it solved in version 3.0 ? If yes how much ? Is it better for me to upgrade my wp version to 3.0 ( because i have high traffic ) ?

    Yes, WordPress 3.0 uses less CPU and memory than 2.9.2, but all of this depends on your definition of “high CPU usage.” Most issue with high CPU usage are usually caused by one of three things:

    1. Poorly coded plugins. Try decativating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

    2. Ridiculously low CPU caps. Some hosting providers, particularly low-cost providers, cap your maximum CPU at a ridiculously low level. This can give the illusion that WP is prone to “high CPU usage,” when in fact the CPU usage is actually low to moderate.

    3. A very high traffic blog with lots of plugins. If this is the case, consider caching.

    How about templates ? Are wp2.9’s templates compatible with V3.0 ?

    Yep, they should be.
