Hello Parvez, 

We could use some more information from you to help us clarify the problem.

When the loading is slow - how long does it take?

Where are you located? 

Please load this page - 

http://www.oddcast.com/support1/sayAudio.html

with the dev tools open & 'network' tab selected & 'disable cache' selected - and send me a screenshot similar to the attached - displaying the timing of the loading of various page components. This would be helpful to understand the nature of the problem.

Hi Yanis - I believe we handled this problem and helped you out via email (at support@sitepal.com).  If you are still having a problem let me know.

Got it.
