Support » Fixing WordPress » HUGE Memory Requirement – Xdebug

  • I just did some tests on wordpress and I found it to be rather large and slow for as cool of software as it is.

    After running xDebug and another custom benchmark class on the script I found that an virgin wordpress 2.3.3 install uses 8744088 bytes (8.7mb) of memory just to show the index page.

    It also takes (on my Athlon 1.9Ghz, 1GB RAM) .70 seconds (almost a full second) to create the page – so for .7 seconds your server has +8mb of memory tied up. It would only take 10 users online at the same time to fill up 80mb of RAM!

    Now, this doesn’t prove a problem for average users who get less than 300 unique visitors a day – but what about big sites? Do they just suck-it-up and buy larger hosts? or are there some things in WP that can be edited/deleted to free more memory?

    I know there is WP-Cache – but what if you don’t want to force your whole pages (parts are ok) to be static?
