A blog that Harry wrote prompted me to go look at what I think is the busiest phpBB board I have ever seen to see how it sits today....
What I saw absolutely blew me away.... They get over 700,000 posts a day now at the board. I looked at one thread that by itself has more than 640,000 replies. Over 60,000,000 total posts and counting on the whole board. At this rate they will be the #1 ranked message board at www.big-board.com within a couple more months (or sooner). They are currently ranked #4.
And what is it running? PHP and using MySQL as the backend database. If you want a good perspective on what the person who codes the site does to tune it (from a PHP, DB and hardware perspective), then read the link below.
I am attaching a couple of screenshots I took tonight. I am just stunned by how much that board is growing. 4 or 5 months ago they were at 200,000 posts/day.

I am curious if anyone else has seen this kind of volume of activity on a site using PHP?
