Warning, this might break your installation. It is for testing purposes only!

I recently came back to looking at pligg, and Beta 9 seems to be to be slower than previous versions. Having run a few checks, it was obvious why:

HTTP Requests: 65
Size: 177kb
Time: 11.60s (ISDN) / 1.74s (T1)

So, i starting gzipping files. First css, then scriptaculous javascript files, and finally general gzip in htaccess. The results thus far:

HTTP Requests: 16
Size: 39kb
Time: 3.20s (ISDN) / 1.01s (T1)

This is using default installation, on the digitalnature template only, with no other modules installed. Brief testing has been carried out, and the main user functions appear to still be working. Load times have dropped dramatically.

Remember, this may break pligg functions! It is not fully tested, I just wanted to say whether i could make pligg load faster. With over 100kb of javascript, 65 HTTP requests, and no stories on the main page, i was a bit concerned about loading. The files (changed and original) are attached below with some basic instructions, if anyone wants to play with them in a test environment.

Demo using gzipped files: http://news.oioplus.com

Update: v1.03 - uses zlib to compress all gzip and js files, uses scriptaculous 1.65


PS. totally unrelated, but if anyone is thinking of / has started a vBulletin bridge, i'd be interested in hearing from you!

I will definitely take a look at this. Thanks.

No problem. First thing i've noticed that doesn't work is the editnplace function. So, it may take a bit of trial and error to find the best balance.

EDIT: fixed, the file scriptaculous.js needed an edit (to add the .gz extention). Also, the file editnplace.js won't work if gzipped. So far, the rest of the functions appear to be working. Updated zip file to v1.01

Simon, how do we check to see if mod_gzip is enabled? i skimmed the httpd.conf file for it and didn't see it. The reason I ask is because I am testing the latest attachment and my sidebar has dissapeared. This is usually caused by some conflicting javascript but I was going to check with the mod_gzip first.

Error on my part, the htaccess file i put in the zip uses zlib, not mod_gzip. If you load phpinfo() on your server, scroll down to "zlib"and look for the row "ZLib Support".

It is probably a js conflict though. I changed 2 js files in the v1.01 update - prototype.js and scriptaculous.js - so you might want to try reverting them. If you revert scriptaculous you'll need to use the uncompressed versions of the files it calls (effects.js etc), since only the modded version called the compressed files.

Updated files in first post to v1.03 - now uses zlib to compress all files to increase compatibility with user browsers (and servers that dont have mod_gzip or mod_deflate installed).
