Here are some tips to optimize your vB3 using vB3's inbuilt optimization features - this would help most for larger vB3 forums:

Tweak the following settings which affect server load the most - in combination they help to reduce server load:

1) Add Template Name in HTML Comments - NO

2) Add No-Cache HTTP Headers - NO

3) Cached Posts Lifespan - 90

4) Update Thread Views Immediately - NO

5) Update Attachment Views Immediately - NO

6) Number of Emails to Send Per Batch - 10

7) Minimum Time Between Searches: 30 (don't leave this at 0 - search is very server-intensive)

8) Automatic Similar Thread Search - NO (this helps A LOT if disabled)

9) Check Thread Rating - NO

10) Check Thread Subscription - NO

11) Show Similar Threads? - NO

Also, in general:

12) Disable search for guests

13) Disable Who's Online for guests

Disabling the above non-essential features will help reduce your server load in vB3 by quite a bit. Try it and see.

Obviously, other things you can disable that may help would be forumjump, memberlist, dot folders etc. but I like those features. The more things you disable, the less load.

I've listed above the more server-intensive features that would help the most.
