Combine Javascript to improve performance
 

Hi All,

I was just wondering if anyone has had any success with combining all of their .js files into one and how significant the performance increase was?

I'm looking at combining everything into the common.js file and would appreciate some feedback on those who have completed this.

Thanks.

Hmmmm,

No one has had any success in doing this?

The effect of this would vary per site. If you have a bunch of things loading, then all the JS files will start taking up HTTP requests and slow the load time due to waiting. It would also reduce the bandwith overhead of requesting more files but that difference wouldn't be noticed by much.

If you want to combine your javascript, you will need to find out which scripts can be combined so they load in the order they're supposed to. This could become more work than worth depending on how much JS is used and how much traffic you get.

Thanks for the response. I currently have a load time of around 2.1 seconds according to Google, yet there are 10 JS files I would like to reduce these.

I'll have a play on a vm and see what the results are.

Im needing to have this done as well but have absolutly no idea how to do it. I think though you only really see a difference if the site gets really busy...

This is true, I'm just looking at reducing requests on the server

This feature is available in 4.4.x. So, consider upgrading X-Cart.
Alternatively you can check 4.4.x code and back-port it to 4.x
