Posts taking too long to load

Hi guys,

I am relatively new to this whole thing, so sorry if I don’t catch up fast enough (just like my posts… hehe).

Anyways. Problem: homepage, other separate pages/categories and contacts are all loading super-fast (well, in a normal amount of time).
But I have a problem with separate posts loading: as in if I click on a post (whether from front page or under categories) it takes forever for post to load.

I use Google Speed Tracer if that’s of any help: it shows that the longest were Pars HTML, Style Recalculation, Layout and Script Evaluation (I have really no idea what I just wrote).

It is possible that I might have damaged something withing CSS myself, of course, but I am not sure where or how to repair it.

Blog is Märkmik(hosted on separate domain)

It’s in Estonian.
Thanks in advance if you could give some advice!
