Loading Javascript : HTTP Requests
I'm having difficulty in deciding which approach is better in terms of site performance.
Either to have all required jQuery plugins in one file to be included on every page on the site OR split the plugins out to individual files and use the jQuery.getScript() method to load them as and when required.
Is there any real benefit in loading the scripts asynchronously over one http request?
All my Javascript will be minified and gzipped.
Thanks!
It's not so simple and depends on the distribution of javascript across your site. Have a look at this question : Which is better for JavaScript load-time: Compress all in one big file or load all asynchronously?
From my poit of view the best solution until now is controljs

One request will be better for performance. Period. Only downside is, every time one of the files changes, the whole thing changes (and will have to be downloaded again). Plugins won't change much, so I'd put everything (as much as possible) in 1 file.
Put jQuery core in that file as well. And your custom javascripts as well. Just make sure it's in the right order :)
