12 Quick tweaks for VPS/WHM/cPanel to speed up WordPress

I am briefly pointing out 12 best tweaks for your VPS/WHM/cPanel to speed up wordpress and to reduce background memeory/CPU usage. WordPress is the best open source CMS but while you use it with more plugins it is a resource hog. Many of us are not actually aware of this but again it is possible that many of you might already get notice from your host for maximum CPU usage or shortage of RAM or for increased server load/bandwidth. If this thing continues, your hosting company might suspend your website/account. This is bad. But there is nothing to worry. If you are already using a VPS, you yourself can tweak the performance of your VPS (Virtual Private Server) from your WHM (Web Host Manager) control panel. If you are unsure about the technicalities, you can ask your host to do these tweaks for you. I am here jotting down the list of tweaks for your ease of understanding. If you want any further explanation regarding any point, you can drop me a comment.

1. Turning Mailman off – WHM >> Server Configuration >> Tweak Settings and turning it off
2. Number of minutes between mail server queue runs (default is 60) – Setting it 120
3. Default catch-all/default address behavior for new accounts” to fail
4. Boxtrapper Spam Trap and SpamAssassin Spam Box delivery – off
5. Analog Stats – off
6. Conserve Memory at the expense of using more cpu/diskio – turn on
7. WHM >> Service Configuration >> FTP Server Configuration – Check ‘no’ to ‘allow anonymous logins and ‘no’ to ‘anonymous uploads’
8. WHM >> cPanel >> Manage Plugins – install spamdconf – then go to ‘Setup Spamd Startup Configuration’ – select option 2 ‘Maximum Children” to 2′
9. Run your cron jobs at off peak hours.
10. Install e Accelerator PHP accelerator (Recompile Apache with eAccelerator)
11. Compiling Apache with mod_deflate Gzip Module
12. Running Apache with the thread-based “Worker” MPM instead of the default “Prefork” MPM
