Tweens & server

Greets.

I tested an incomplete flash site im working with on free hosting server and noticed that tweening masks & animations play generally slower than running/testing on Flash in my computer.

Site SHOULD run just as smooth played in server as testing in my computer since I ofcourse accessed to the server with my very same computer, yes?

I use rather high FPS of 60.

Should I use more actionscript instead of tweens or perhaps just reduce FPS?

Thanks.
