# Last advice

This new version of the Newbb forum is thus impressive by the number of the functionalities which it has, but all that has a price. Activate for example the debug mode in mysql/blocs version and observe the number of requests generated on the main page of a forum.

If your site is higly visited and the power of your hosting is not adapted, the activation of all these innovations is likely to slow down the rendering of pages of the forum when many visitors are present simultaneously on your site. This is why it will be necessary for you to be attentive with determining well what seems essential to you compared to the comfort options to obtain the best compromise.
