[Phpwm] [phpwm] Best js compression techniques?

[Dave Holmes]

Echo everything David suggests is good, just to add to that list there
is something I have mentioned on list before which gave us a massive
boost. 

We used to have a lot of JS files which we used to segment and
modularise our code just to make it manageable - the down side to this
was browsers download JS serially to resolve dependencies and  not in
parallel like other page assets. Combining multiple JS files into one
then minifying will help you out also. 

If you are using a build process of course you could get it to
concatenate your nice manageable files into one and compress.
