For an update.
After installing the cache cleaner button. I too was getting greater than 10 second load times, not even I would use a site that took over 10 seconds to load!
So, I enabled zlib compression on my server. To this, I opened my php.ini file on the server, search for zlib. Found the zlib settings and edited it from "Off" to "On". Then I restart apache. This improved the page load by about 2 seconds, that was according to the WSO site I mentioned earlier in the post.
Next, was this
CSS compression technique. This was a little harder. It basically balls up all your CSS files into one file. Less round trips to the server, less pages to process on the local machine, faster load. This shaved close to another 2 seconds off the load time.
Next will be a similar trick.
Javascript Compression I already have the code in place, just getting some squirly behavior on my local machine. Think has to do with multi threading.
The only other thing
I can do is use "sprites" which I don't have time for. The other recommendations the WSO is pointing out are not possible. The site relies on Mootools which is a large file, even when compressed, so my JS size keeps taking a hit.
After restarting the Apache server to clear its cache, and clearing my browser cache, I get consistent load times under 7 seconds.
Anyone get anything grossly different?
I can live with that for now. I've also identified several files that the CSS file is looking for that don't exist. I need to weed out these requests in the CSS file. Between these files and compressing the JS down a bit more, I'm hoping to reduce another 2 seconds on the load time.
Keep in mind, right now it's under 7 seconds in a worst case scenario. For a revisit, the page loads in under 3 seconds for me.
