So I changed lots of things last night. Disabled some settings. Got rid of quick navigation, member list, customized profiles, VBexperience add-on, as well as other minor things. My members say they have noticed some improvement.

I stayed up all night and never got a vbulletin database error (usually happens every night between 1-4am). So I'm happy with that, but we'll see... might have been a fluke.

Has anyone tried this?

https://developers.google.com/speed/

I just used it today and my score is 64/100. Could be better.

The Page Speed Score indicates how much faster a page could be. A high score indicates little room for improvement, while a lower score indicates more room for improvement. The Page Speed Score does not measure the time it takes for a page to load.

Then it lists, in order of priority, changes I should make to improve my page speed. Based on the results, it's my guess that these are things anyone with a vbulletin forum would also have issues with. Does anyone know how to do these three things?

The high priority items:

1. Enable compression:
   I already did this the other day by enabling gzip html output and using a compression level of 1.... so I don't know how I can improve this further? Here is what it says:
   
   Compressing the following resources with gzip could reduce their transfer size by 145KiB (76% reduction).
   
   Compressing /clientscript/vbulletin_css/style00001l/main-rollup.css?d=1332834548 could save 55.6KiB (82% reduction).
   Compressing /clientscript/vbulletin-core.js?v=4110 could save 35.7KiB (70% reduction).
   Compressing /clientscript/vbulletin_css/style00001l/cms-rollup.css?d=1332834548 could save 26.2KiB (79% reduction).
   Compressing /clientscript/vbulletin_overlay.js?v=4110 could save 10.6KiB (75% reduction).
   Compressing /clientscript/vbulletin_lightbox.js?v=4110 could save 8.8KiB (73% reduction).
   Compressing /clientscript/vbulletin_md5.js?v=4110 could save 3.4KiB (63% reduction).
   Compressing /clientscript/vbulletin_cms.js?v=4110 could save 2.4KiB (59% reduction).
   Compressing /clientscript/vbulletin_ajax_htmlloader.js?v=4110 could save 1.2KiB (61% reduction).
   Compressing /css.php?styleid=1&langid=1&d=1332834548&sheet=ss_r ightcolumn_css.css could save 717B (59% reduction).
   
   
2. Combine images into CSS sprites - I have zero clue on this one:
   
   The following images served from *******.com should be combined into as few images as possible using CSS sprites.
   
   /images/buttons//lastpost-right.png
   /images/buttons/search.png
   /images/cms/read_more-right.png
   /images/cms/widget-forum.png
   /images/gradients/selected-tab-gradient-with-top-alpha.png
   /images/misc/arrow.png/arrow.png
   /images/misc/black_downward_arrow.png
   /images/misc/blog/gradient-black-down.png
   /images/misc/blog/top-highlight.png
   /images/misc/navbit-arrow-right.png
   /images/misc/navbit-home.png
   /images/misc/unknown.gif
   /images/pagination/last-right.png
   /images/pagination/next-right.png
   /images/site_icons/html.png
   
   
3. Leverage browser caching - also no idea
   
   The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:
   
   /images/buttons/lastpost-right.png (expiration not specified)
   /images/buttons/newbtn_middle.png (expiration not specified)
   /images/buttons/search.png (expiration not specified)
   /images/cms/read_more-right.png (expiration not specified)
   /images/cms/widget-forum.png (expiration not specified)
   /images/gradients/gradient-grey-down.png (expiration not specified)
   /images/gradients/selected-tab-gradient-with-top-alpha.png (expiration not specified)
   /images/misc/arrow.png (expiration not specified)
   /images/misc/black_downward_arrow.png (expiration not specified)
   /images/misc/gradient-black-down.png (expiration not specified)
   /images/misc/top-highlight.png (expiration not specified)
   /images/misc/navbit-arrow-right.png (expiration not specified)
   /images/misc/navbit-home.png (expiration not specified)
   /images/misc/unknown.gif (expiration not specified)
   /images/misc/vbulletin4_logo.png (expiration not specified)
   /images/pagination/last-right.png (expiration not specified)
   /images/pagination/next-right.png (expiration not specified)
   /images/site_icons/html.png (expiration not specified)
