How can I improve the load times?

[SubStrider]

Hello guys,

This seems like a really good tool and I have optimized quite a few things since yesterday. One thing however got me worried is the load time from different locations.

Here is the test result from a US test server -> http://www.webpagetest.org/result/120127_1P_31118/

Here is one from a Singapore server -> http://www.webpagetest.org/result/120127_NR_31100/

The primary userbase is in the Indian subcontinent so am not sure that the first result is anything to be happy about. In the second result, the repeat view actually takes much longer

Can you guys tell me what all can be done to improve the performance.
