Where to order website optimization (not SEO, but speed)?

Question

Server optimization

What companies are involved in website optimization? For example, you need to analyze the speed of work, find the causes of problems and eliminate them. All within the framework of the slowness of the site.

Answer 1

yes, this is easily done. You just need to know your CMS and find a specialist in this particular CMS. Of course he must be Prof. developer, not couch webmaster. It also optimizes the speed of your work.
Part of the audit can be done even by an ordinary mediocre programmer. It will analyze the sizes of images, css styles, etc. and the speed will already be better by reducing the weight of the layout. And then let the proger optimize.

Answer 2

The usual programmer is necessary.
Not a schoolboy and not the one who has been a freelancer since birth and has not studied with anyone and doesn’t know shit.
And normal.
That is, any experienced programmer.
If you have Highload, then specific skills are needed there.
And for an ordinary site, an ordinary programmer is suitable.
As it was rightly noted here, the one who specializes specifically in your technologies is better.
If you have a CMS, then it's probably just enough to set up caching in it.
In the middle between a regular site and Highload, they accelerate something like this:

This is not for a ready-made recipe, but just see how a person was looking for a problem.
This is within the power of any experienced programmer.
