The other day talking with my dad on Facebook, he asked me, why my blog is so slow today - it's so slow that he cannot open my site at all. I straight went to my Linode VPS to investigate server logs. Nothing unusual did find there. I used http://tools.pingdom.com/fpt/ to test speed of my site and it actually was really slow.
Since my blog is heavily based on Drupal views, and I had not before enabled cache neither for CSS or JS (I'm still not aggregating CSS and JS) I decided to give a try and to enable cache for all of my views.
The result? Pretty fast right now.
But yes - enabled views cache did help a lot :)
How to enable Drupal views block cache
Drupal views block cache
Under Other change Caching from None to Time-based. In next window choose your cache time from a drop-down menu.
Basically that's all. Just clear your cache and head to http://tools.pingdom.com/fpt to test is there some improvements.
