Be Careful! Wordpress Themes Consume more CPU Power
You might be in a shared hosting plan and most hosting providers allow CPU usage only to a certain level. Be careful that many wordpress themes (including commercial ones) i have seen can take more CPU power. If that is the case the hosting provider may suspend your account. I had a situation with bluehost where you are allowed to use only 40% of CPU in a 140 sec window. If your site consumes more than 40% of cpu with bluehost you will get “CPU exceeded” error. You will have to wait for 5-10 minutes for your site to go to normal.
If your wordpress theme uses more SQL queries which means it causes mysql server to put more load on CPU and your hosting account may suspended . I have seen many wordpress news/magazine themes use more unoptimized mySQL queries in the frontpage.
Be careful! on the wordpress theme you select.

This is very true - it’s well worth looking at the source code of a theme demo and searching for the word ‘queries’. A good coder is proud to keep things optimised and you should see under 30. Any more and something bad is going on. Time wise look for a target of around 0.25s, though this obviously varies with server load.
Not all themes output this information, but we make a point of doing so with ours because it can help with analysing problems. Plugins can cause issues too so beware overloading a site with them.
