RussianQuestion
I'm looking to scale an existing phpBB installation by separating the read queries from the write queries to two separate, replicated MySQL servers. Anyone succeeded in doing this, specifically with phpBB?
The biggest concern I have so far is that it seems like the queries are scattered haphazardly throughout the code. I'd love to hear if anyone else did this, and if so, how it went / what was the process.
Solution
Just add more RAM. Enough RAM to hold the entire database. You'll be surprised how fast your inefficient script will fly. Memory forgives a lot of database scaling mistakes.
OTHER TIPS
You could try MySQL Proxy which would be an easy way to split the queries without changing the application.
I know this was asked a long time ago, but I'd like to share what I experienced, in case it can help anyone.
If your problem are table locks, and knowing that the default storage engine of phpbb in that day was MyISAM, have you looked at moving to InnoDB storage engine?
Just find out which tables are most frequently locked, and convert those to InnoDB. The sessions table is the first candidate here, although you may want to look at other optimizations (such as storing session data only in memcache or something) if that is your main bottleneck.
