A very interesting article of how someone fixed GTA V loading times by fixing their JSON deserializer. He improved speeds by 70%, and got awarded 10k from Rockstar, and Rockstar actually implemented his fix in an update! Cool story :)

How to reduce the latency of x? Just go through the code of x and make it do less things! So don't shy away from trying to peek under the hood of the functions and etc that you are using. See how they work, and see what can be skipped.
