Low site speed | pages are loaded slowly

Evening, gentlemen!
I have a problem with my site:pages are loaded very slowly http://allada.org/kursy/
Especilaly this page: http://www.allada.org/kursy/raiting
I tried to turn on cashing, but it didn't work!
What can I do to fix the page load speed?

From amsterdam test:

From USA test:

It seems alot slower in the usa. Try also to check with your provider.

On my pc it does load fast!

HI

It loads fast for me too, but I always advice to use jotCache to speed everything up. That's the best cache solution for joomla I know.
