Hello.
Only some .js files are gzipped and cached by the browser.
The 2 .css files that you send to the browsers are neither gzipped, nor cached.


This comes in the .htaccess file in the forums main webserver-directory.
I tried much, but this was best i achieved so far.
It is always best practize to gzip ressources directly through Apache rather then the applications installed on server (forum software).

This is the Start-Page of USmessageboard.
You can optimize the images at Yahoo's "smush.it" without quality loss.
Also the images loaded from theme have no expiries set, meaning browsers load them every time.
In above .htacces it is covered.

This is Yahoo-Yslow performance analysis of front-end of one of my websites:
100 is max.

The score for USmessageboard, I wont post.
I don't want to meddle in your things.
But with little work, you could optimize front-end load of website, like caching pictures and scripts, gzipping scripts.
Minimization of scripts and combining them to reduce DNS-lookups would need more "work".



From Yahoo:
Remember that 80-90% of the end-user response time is spent downloading all the components in the page: images, stylesheets, scripts, Flash, etc.
This is the Performance Golden Rule.

LINK: Yahoo - Best Practices for Speeding Up Your Web Site


You make 21 HTTP-requests on Front-Page.
Depending on each Users settings for paralell downloads in their browser-settings, this is - like Yahoo says - the area to achive most results in responsiveness of front-end.
That would need the HTTP-requests to decrease, which is achieved by combining the scripts which make the HTTP-requests.



P.S: Sorry for meddling in your business.
And I do not take any responsibilities, if you try something mentioned here.

Above i mentioned several times Gzip, but actually in the -htaccess is used Deflate method of Server.

Deflate is always faster then Gzip.
This has been tested everywhere over internet by geeks.

This guy for example achieves 41% better results using Deflate method over Gzip

So above is already Deflate if you use that .htaccess

You have issues, don't you?:eusa_eh:
I've found over the years of dealing with and working with folks such as this one in the OP, that generally they are correct. This one is as well.

However, most of the time for some reason, they expend tremendous energy and thought addressing a problem you really don't have or is one which isn't really all that relevant. This one is as well.

Some never learn "a difference which makes no difference, is no difference."

Pictures are worth a thousand words &#8212; especially on the web, where pages of text can download in the time it takes for a single image to load. Your images may be sub-zero cool, but if they&#8217;re too plump, few people will stick around long enough to see them. We&#8217;ll dig into tricks and optimizations to speed up your GIF, JPG, and PNG downloads.
Once you&#8217;ve learned the basics of shrinking your images, we&#8217;ll will walk you through the advantages of using CSS for your page layout. And, if you&#8217;re one of those people who insists on using tables, we&#8217;ll offer you a few choice hints on how to get those tables slim and streamlined. After you&#8217;ve removed the bloat from your layout code and your images, you&#8217;ll learn how to cut needless elements from your pages. Hint: Start with all those links. The series concludes with wise words about how to come up with benchmarks for speed and how to test your site using nothing but a stopwatch and a pencil.
