Magento Performance Optimisation
There are many ways to optimise Magento Performance, broadly split into the following categories:
This is a stub, the page needs a lot more content adding
Server Side - Time to First Byte¶
This is how quickly Magento receives a request and then returns a response. The "first byte" is the very first byte of response that is received by the browser after making a request
This is the speed with which the browser can retrieve all of teh assets for a page and then render them
This metric is what is being tested when you run tools such as Google Page Speed
Server Side TTFB Techniques¶
Prevent Modules from Phoning Home on Front End Requests¶
Some module authors, especially paid for modules, have taken the decision that they want to build in licence checking code which will actually make a web request into the rendering of front end pages.
This can add a number of seconds on top of the standard TTFB. If for any reason the remote server is slow or not responding then the impact can be huge.
