Of course this will need good servers with good hardware specs and good amount of RAM but that is what most good shared hosting accounts provide today.
That's correct! Probably, if you
understand that, I will open a secret... we just don't want to have big problems with big users :-) Sometimes, when a project becomes popular, server loading is too high. Any script will execute slow - but not everybody understand that he must upgrade the hardware, not software :-) Of course, using native procedures and database requests should give good results even on large amount of data... but we are just planning to make miniBB as "software for ages" - for example, big amount of posts produces some special "archiving" feature, which is not ready yet, when, for example, you may separate old posts from new and make loading of database more faster. We are still working on that - and just don't want
to propagate miniBB as superb script for large forums this time. But we are having this in mind :-)
Check, for example, russian forums on WASM
or even ForumForever
- 70,000 and 150,000 posts are not bad, but Statistics, for example, is sometimes loaded too slow. Just because mySQL is not able to handle inner selects or count() operations on large amount of data...
