To optimizirovat

Is there a site after development which revealed that he is starting to be loaded after 2.5 seconds. Found a piece of code which functions.php increases the time before the download site here is the code wp_yf()->check_payments_schedule(); it was determined that this code is responsible for returning with the payment system, the response to the Website on successful payment and updates the balance amount. The programmers didn't do it right hook you have to redo to get this Feature to work without loading the website. Also found a couple of problems since after documenting this piece speed plugin download becomes 3 seconds , 1.4 – obviously there is still something that hangs Heavily website. Objectives: 1) to rewrite the problematic pieces of code or to optimize (which they do not give a load about the payment system code which gives the load is digiseller.com there is a document in the connection API.) 2) to configure redis (to write the instructions how can we do this on another server) 3) configure the plug-Ing caching like Super Cache (if you just include it caches a balance and so forth need to make what specific data do not cache, the quick settings don't work) Need people who know programming in WordPress, not just know how to install plugins.
