If you are making use of usual collections (such as jQuery, Prototype or Dojo), you can unload the documents to Google and also make them serve it, this offers you numerous benefits:

  • You do not need to bother with minifying and also whizing etc
  • It's not your transmission capacity
  • These documents originate from a various domain name, so you can (at the very least partly) workaround the limit of 2 parallel requests per hostname
  • If you're fortunate, the customer has actually currently seen a few other website that made use of the very same collection from the very same carrier, so they currently have it in the internet browser cache.

Keep in mind : The variation you request for can have a huge influence on the caching features : requesting for jQuery 1.4.2 will certainly offer you a documents that can be cached for a year, yet 1.4 can just be cached for a hr.

In enhancement to the solutions over, you can make use of the Google Closure Compiler to instantly compress and also maximize your JS while incorporating with various other 3rd event collections (jQuery, YUI, mootools, etc)

You can place the entire library right into one js documents and also compress the documents. Nonetheless, it actually just matters for the first loading of a web page. Hereafter your js documents will certainly be cached in the internet browser, specifically if you set the cache - expiry enough time. Therefore any kind of successive hit will certainly not load your js submit any longer.

There are 4 points you can do.

  1. Minify your JS File. This gets rid of all remarks and also Whitespace to lower its dimension.
  2. Incorporate your JS Files on each web page to make sure that there is just 1 documents.
  3. Make use of a plan to gzip your documents when you send them. This will certainly make them also smaller sized
  4. Put Javascript that isn't called for quickly at the end of the web page to make sure that it lots at the end. This will certainly permit the customer to see and also make use of the web page also prior to the JS is entirely filled.

And also a few other individuals have actually recommended:

  • Apache will instantly take care of compression (and also caching of pressed web content) which greatly streamlines monitoring of documents
  • Making JavaScript effectively cache - able will certainly generate large advantages.
  • Wildcard domain names (with numerous URIs) will certainly permit extra simultaneous links. Pre - bring is not simply for photos/

If you have a variety of web page components & accessibility to different domain name, you can take into consideration organizing all fixed documents consisting of the huge JS documents on the 2nd domain name.

As Steve Souders notes in his High Performance Web Sites blog -

... in some scenarios, it's rewarding to take a number of sources that are being downloaded and install on a solitary domain name and also divided them throughout numerous domains. I call this domain name sharding. Doing this permits even more sources to be downloaded and install in parallel, lowering the total web page load time.

in other places he creates.

Internet browsers open a minimal variety of links per domain name ... Splitting, or sharding, the demands throughout 2 domains, in contrast to one domain name, causes a much faster web page, specifically in IE 6 & 7
