VS-3 optimizing a VPS

Hi Guys,

I am the owner of the VS3 package here at knownhost and i am looking for tips on how to optimize my vps to improve the speed of my main site.

I host several sites on this host, but they have low traffic each, probably 10-40 and some of them are html only, no DB.

My main site is a games portal that has around 2000 UV per day, and i need to improve the speed, now is decent but i need more speed:

Info on the site:


- Created on Word press engine
- Site is dynamic, all query from DB, it has some popular scripts which counts the visits for each post, for queries.
- it requires heavy js on some pages.

What i did so far:

- subdomains for different types of content around 3, static(images), video and js, and so on.
- optimize the js loads for each page.
- running a PHP thumbnailer for thumbs, it creates a cache version on first load and loads the cache from the server on second load
PHP Thumbnailer from Gen X Design
- optimized parts of the word press engine for faster load
- i tried to use w3cache but overall it doesnt work good, since google starts to index cache pages, it has problems with some of the things i did to the site, and it uses a lot of sources when it generates the cache.
- optimize the DB from time to time.

Overall i think i will have to improve the speed, optimized the DB, since everything is dynamic. Unfortunately i only know only basic things on server, how to run them, and a few tweaks there and here.

If you have any hints and tips, let me know, thanks
After writing the post above i went to work for 12 hours, and i reduced my site speed from 12 secs to 4-5 secs:)

In the end if you want to do something just research, debug:)

Now i am happy:D
Very nicely done idragon!

Perhaps you could share with us some of what you did?
1. I installed YSlow plugin in firefox and page speed plugin. I started to analyze what are the objects, files that breaks my domain speed,. To view a detailed progress when loading refresh the page while having the yslow open with tabs (Net > All )

2. With these tools i noticed that something breaks the domain on load on the first 4 seconds. Analyzing the code and DB, there was a problem with some stats, and optimized that.

3. I toke all my 4 .js files and compiled them into one so it loads only one .js instead of 4.

4. I added expire headers in .htaccess :

<ifmodule mod_expires.c>
<filesmatch "\.(ico|jpg|jpeg|png|gif|js|css|swf)$">
ExpiresActive on
ExpiresDefault "access plus 6 months"

5. I cleaned the code on the first page with conditional functions to load only what i need for the first page.

I started to read good resource like:


6. I ran a diagnostic with cpanel/whm on Apache and it increased the memory to 64 mega.

7. DB Optimization and repair.

= Epic Win!

I still have things to do, but for now the site loads much faster.

Hope it helps
