Instead of loading the entire package information, it simply loads the description, which is all I need to know about the package I'm looking at.

To do this:

Create a backup copy of /Applications/Cydia.app/package.js and copy it to your PC/Mac using a file transfer method (SCP for example).

Open it up, find the line that reads (it's on line number 208 of the file):
var depiction = package.depiction;

Change it to:
var depiction = null;

Save package.js and upload it to your iPhone in /Applications/Cydia.app/, over-writing the old one.

Restart Cydia, load up a package, and enjoy the increased loading speed!

If you don't like it, you can do the reverse of what I have said here, or simply copy over your backup copy of package.js

Let me know what you guys think! :hooray:

EDIT:
You can also use iFile to do all of this right on your iPhone if you have it installed, just make sure you create a backup of the package.js before you edit it!
