Sporter is slow and have some design issue

Team,

My site http://www.tkthub.com is very slow, it takes 20 to 30 seconds to load. I have not used any extra components/modules in my site and i have around 220 articles in K2 component items. Why my site is slow?.

Also i have design issue on tag news area.
for example
http://www.tkthub.com/Theatre-Tickets.php

If you click any link in tag cloud area on above page, that page have not aligned proper like footer.

Could you team have a look and let me know the problem
