Thanks, though I found this late (rather I started looking for such articles really recently), after reading this and a lot of other blogs and slides, I thought about how to cook up a javascript aggregate plugin for wordpress. The out come is wp-jsmin. Though this is in its infancy, it is being used at PHP Trivandrum just as a test base.

when trying to use your adapted version of the script with the PHP version of JSMin I am running into 2 problems:

1 - I need to change this code sCode = $jsMin->minify(); into $sCode = $jsMin->minify(); to get it to work to some degree

2 - then the source code in the browser would say something about Warning: filemtime() [function.filemtime]: stat failed for /home/bla/bla/bla/somejavascript.js in /home/home/bla/bla/bla/combine.php on line 107

line 107 in your script is this line in my file: $aLastModifieds[] = filemtime("$sDocRoot/$sFile");

any help would be appriciated to help resolve this issue

thanks in advance ! Josef

[…] Cod optimizat — toate spatiile din codul HTML care nu sunt necesare sunt eliminate, la fel si Ã®n fisierele CSS rezultÃ¢nd o dimensiune minima. De asemenea si codul PHP, din spatele website-ului este gÃ¢ndit Ã®n asa fel Ã®ncÃ¢t sa foloseasca cÃ¢t mai eficient resursele serverului. […]

Couldn't you also introduce the concept of memcached in addition to the practices mentioned above? It would limit the the network calls on remote files, and could retrieve data much faster. This solution is obviously more server side, like gzip of deflate.

Hi Pim, thanks for the contribution! You are right, and there are even more techniques I wrote about in part 2 of this article. One of them concerns zipping content, though Nate Koechley stated that gzip is more efficient and better supported than deflate.

I think another good addition to speed up your website is apache2’s moddeflate. Now my commented mootools is 180kb. When using moddeflate and JSMin (php) it gets down to 18kb!. Offcourse while using a caching mechanism to prevent obfusticating the JS each time a user loads any page. Same counts for css.

SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar|swf|flv)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .pdf$ no-gzip dont-vary
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch bMSIE !no-gzip !gzip-only-text/html

Jens, thanks for the useful links, I will check them out. Concerning the "inline" styles: although they appear inline, they are maintained as separate CSS files and automatically merged with the main document on the server side.

Good points (except that inline styles are almost never advisable in terms of "philosophy" and maintenance […]) — we should be happy about everyone emphasizing performance in times of homepages with 500+ KB size and 30+ seconds load time via 56k (that’s far from gone anyways).

Concerning CSS compression, though, try Peter Bengtsson’s code compressor to manually compress style sheets. Little awkward but “robust.” And concerning CSS and multiple style sheets — I recently suspected “print” targeted style sheets to be fetched on document load (which also makes sense anyway) — and which surely supports the recommendation to use a single style sheet.
