WP Super Cache and very weid things.

I GIVE UP.

I have VPS, configured him to using only 50mb – nginx, php with fastcgi, mysql and exim4 are only installed. I installed WordPress on this server, I have added post, configured WP Super Cache, well… I was thinking I did that right, but now I don’t think so.

Everything would be good, but after turning on, and visit some posts, pages my VPS is getting busy, and when post is open and I can see content it can last for about 10 minutes, and page won’t load… After 10 minutes I see 504 error page, and to see our page only is restart php by console…

My phpBB is ‘getting furious’ I mean it is loading in 0,03s and I do not have any problem with this script, I won’t wait 10 minutes to load forum topic or something else connected with loading.

It is a horror, that WordPress has caching problem, but I think that WordPress as script isn’t good, and has a lot of bug, for example can use caching and loading time.

Next thing as I can tell is my WP Super Cache doesn’t create cache, I do not see any files in /cache/ folder, even after using Preload option. What shall I do, to do something with this WordPress?

It’s obvious WordPress should working good without any plugins, and WP Super Cache can be only a plugin to do WordPress faster, better more, but not a huge difference after installing…

PLEASE HELP ME!
