Speed

Hello,
My website is here: https://bitsol.cz/

I have been wondering about speed of site.
I see that with Sydney Pro my site is quite slow. Most importantly it is slow in first byte.
I have tried turning on and off varius plugins yet the most important was probably the theme itself and caching on second plugins on second place.

I want to ask whether there are other themes you would reccomend and how much is the webhosting important? I am not paying for a dedicated server. Yet I should have pretty good hardware with SSD that web server is on.

Other things I thought about are about ways to optimalize minifacation of CSS Java and so on.

This is something eveyone has to optimalize on its own?

Generely I am asking about advice on what can be done to make this site into lot faster site that google likes (https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fbitsol.cz%2F)

Hi,

First install EWWW and optimize your images. Then install W3 Total Cache.
Here’s what our demo page is scoring (while being a full demo).

Yeah, but EWWWW uses php_exec am I right?
Is there some plugin that is able to work without it?

My webhosting is not alowing exec
