I'm using following latest files,

jquery.min.js
jquery-ui.js

When I create javascript functions based on above both files, that works well on localhost, but as I upload them to server for become online it goes slower 'n slower 'n slower.

Why scripts goes slow on effects?

I have tried multiple hosting including free hosts, but scripts works well only on localhost.
Why it happens?

Hi,
Maybe the problem is with your browser or operating system. JavaScript runs on client side browser.
If you can, try chen with other computer.

I was thinking same.
I have already tried my two major projects on various computers. They works well if it is localhost.
Whenever it goes live speed of animation goes down

no, currently projects are not live due to it's slower working.

did you test it on other than 'that' browser -is it consistent accross vendors?

I have done cross browser testing with all available browsers. But problem is same script work well on only localhost and goes slower on any type of webhost- windows host or linux host.

Animation Speed Problem occurs only when website goes live.

I will provide link if I made it live.
