Not tested for all Drupal Installations, so advanced users might like to go through these and correct some of the techniques I use.
I’m sure you’ve all noticed upon a fresh installation of Drupal, the cms is super fast, allowing you to instantly switch to different pages and nodes, provided that your hosting environment is fast.
Speed is an important fact in webpages, because with so much competition, users may not wish to wait that extra 5 – 10 seconds, for your jam-packed featured pages to show.
So having used Drupal for over 6 months, in this time period, I’ve learnt a few lessons of what can bog down the pages. So I’ll go through some common ones and techniques that can help.
Many of the techniques require either an ssh connection to the server, so please contact your administrator to make the changes accordingly.
First A few hours ago I typed top on the server, and that resulted in a load of 30.!!!
As I just installed the image block for imagegallery, I knew that this was affecting the performance, so I went into admin/blocks and disabled imagegallery
2 minute later I typed top, and the server figure dropped to 6.3, which was still very high.
As the webpage is a Medium traffic site, I knew that there was some modules I had to let go of, many of these modules will be fine for low traffic sites, but for large sites, they can clog up the site.
