Even with just 2 forums, by installing this mod, you will cut your memory usage in half (providing your using an opcode cache like APC, Xcache, or eAcc)..

I do want to take an opportunity to clarify something I think may be unclear.

When you install this, you define a license key for each site using the DLS system by entering in the license #. This license # that you enter will be used throughout the script for the site it is defined for. This in no way bypasses any licensing methodology in the script. If you enter an invalid license # or a license for a different site than what you defined at vbulletin.com, it will still throw up the red flags for Jelsoft.

The only thing the plugin does is make sure the proper license (as you define it) is returned when called. We contacted the VB team about this and they detailed to us where these areas were so we could build this system without stepping on any licensing issues when it came to their piracy protection schemes.

If you try to use this to have multiple copies of the same license running, it will still be identified exactly the same way it would if they were separate installs.

I wonder if this would work on Windows servers ... I suppose not ... (sigh) ;)

This is brilliant. Thank you! :)

Probably not, at least out of the box. I suppose you could use shortcuts instead of symbolic links and then it would work.

We finally got this working with VBSEO... If you upload all the files for vbSEO to the DLS except for the config file, run the php-clone.php script, you should be all set. Really speeds things up!

This really sounds great!

Great! Don't forget to mark installed if you find it useful. :)

Where do you put the path to the forum in? there is one line in php-clone.php that says Path to the forum not forums, which path is this?

Edit: and also how are you able to upgrade the databases or is it just files this updates?

I've tried it. Shortcuts won't work. So that's a Linux-only solution ;)
