Deriving the maximum out of the created PHP application is something all developers will try to achieve. There are a number of ways using which you can ensure high performance of your PHP application prior to diving into code refactoring. Even if you require profiling your PHP code, you can condor following points to get maximum performance.
Cache In On OPCache : PHP is interpreted into opcodes (executable codes) that allow rapid development & testing without causing any pause. DO remember that recompiling the identical code every time it runs on your site will prove to be highly slow & inefficient. Opcode cache has been an effective solution to counter this slowdown though. These caches save the compiled code output into memory by forming hooks into the compilation system. Out of all these caches, APC or Alternative PHP Cache is the most famous one.
Looking Beyond your Application - Finding out the exact reason causing your PHP application to slow down is not a highly complex task. Initially, you may think your PHP to be the reason for it; however the reason could be something else especially when you have implemented the opcode cache. While accessing external resources. many of your app hurdles come into existence; database delays being one of the major suspects in this regard.

Typically, database relays account for almost 90% of a PHP application’s execution time. Hence, for all database access instances, you need to review your codebase. Firstly, turn slow SQL logs on and then proceed further to query the queries to find out if these are efficient enough. Find answers to questions like - are too many queries being made, are there queries without a suitable index ? Just by giving some time to fixing queries, you can reduce your database access time besides increasing the application performance.
Keep Note of All APIs : There are a number of external resources that developers in every PHP web development company in India & abroad make use of for creating web applications, external API being one of them. Its quite tedious to grab control over the performance of remote APIs being used. However, its always possible to mitigate the API performance effect in the code by caching API output. Protecting your user from a misbehaving API should be your goal ideally. Also ensure that for any API requests, reasonable timeouts are arranged suitably in place.
