How to throttle use of a specific query to an LAMP based CMS

Our D开发者_开发技巧rupal CMS calendar crashes if too many users try to access at once. Is there a way to throttle requests to the calendar to x number per minute etc?

There is a module that will Throttle drupal. It is one of the Core modules, in fact I think its called Throttle.

It sounds like you need to employ the use of caching. Admin / Configuration / Performance -> Enable CSS/JSS aggregation. Download the Boost module to create static HTML files of the website to serve up to anonymous users. I don't know anything about your site, but if no one has to log in, Boost will help you big time.

This should alleviate/help your bottleneck. But we need to know more to provide better direction.
