DC2NET Links

My site (http://www.techhamlet.com) Seems to be loading fast when i check with GTmetrix and Pingdome.. But, in my side, it takes some time to start the loading process! I mean.. when i put the URL and hit enter.. In chrome, the rotating icon goes slowly for some time (This time period is slower than other sites) and then loads fast… Its like it takes time to resolve DNS.. (Im using Open DNS in my home PC)

Any one know whats happening? Any help?

Thanks
