Congratulations Ian on reaching a milestone 10,000 Posts! 7.92 posts per day an over 21% of all posts ! - Wow! I'm sure I speak for everybody here when I say thanks to you and the rest of the DP crew, this is a great site and certainly my fav for this sort of thing. Here's to the next 10,000 . . .if your keyboard doesn't give up beforehand!
I checked the admin panel, did not SSH into server and check MYSQL so these are 'rough' sizes:
Database size: 177.41 MiB Number of posts: 46246 Number of topics: 4406 Size of posted attachments: 1.24 GiB Number of attachments: 7557 Board started: Tue Jan 25, 2011 9:18 am <<remember we were Simple Machines Forum for years before PHPBB3, though all old posts and attachments were migrated to the new forum.
I have not plaid with phpbb3 for a while but iirc you can turn off phpbb indexing and let it use mysql's text search. donno what's faster (I was always running the phpbb's index as disk space was really never an issue) ... on the other hand I see many phpbb disabling internal phpbb's search completely and adding just a "search via google" option to the site as search kills the performance quickly (on high traffic sites) so off loading that to google makes sense :)
