By the way, after minifying, my server response remains 2.6 seconds ??

Even my admin section gets quite slow… sometimes I try to publish, or update, something and it even fails.

Does it mean I have a problem with my hosting service or can still be something fixable in WP?

By the way, I got a better grade; thanks!

Hm, so you are talking about a real manual work, not automatic… I see your point.

I realize now that the old layout required 528×325 XD

Ok, so I from now on I’ll be uploading smaller sizes! Thanks!

But still, I don’t think it is the real damaging thing (still a problem, obviously).

How do I effectively work on:

(L)Minify CSS
(L)Minify JavaScript
(L)Minify HTML

As I stated, I tried plugins like W3 Total Cache, and in the end I always feel like it is getting worse – someone just took 10 seconds to get to one of my pages!

Hello, dear Alen!

Let’s go step by step, if you please… I’m a real beginner with websites!

How do I fix:

(H)Serve scaled images
(H)Optimize images

My website has a lot of images as you can see and my image result was even worse, so I started to use Photoshop to resize the pixels and KiB of every image, but it wasn’t enough!
