My experience with mysql vs postgres is that these days, depending on what you are doing postgres can easily beat mysql on a single box system, but when it comes to replication mysql wins hands down. Slony is a complete dog. Once you move past a single box postgres has severe problems.

One of many examples of data comparing PostgreSQL vs MySQL performance. This was from the end of 2006, so it’s recent enough compared to outdated info from 2000-ish showing how fast MySQL is (e.g. especially without transaction support back then). Now that MySQL has been adding features, it’s closer to comparing apples to apples. If you’re interested, since you said you wanted data showing how PostgreSQL scales vs MySQL.

Very interesting.. Why did you go with mysql replication instead of mysql cluster with 2 active nodes?

Is there an automatic failover between both database nodes incase of a failure? Are you using DRBD with heartbeat?

Hey… just wanted to throw some links out there re: PostgreSQL scaling.

The last link has a couple of nice highlights of the most recent release:
“Performance improvements: version 8.2 improves performance around 20% overall in high-end OLTP (online transaction processing) system tests. Users can gain even more in data warehousing efficiency. The changes include faster in-memory and on-disk sorting, better multi-processor scaling, better planning of partitioned data queries, faster bulk loads and vastly accelerated outer joins.

Warm Standby Databases: through an extension to our Point in Time Recovery feature (introduced in version 8.0), administrators now can easily create a failover copy of your database cluster.

Online Index Builds: index builds can now occur while applications write to database tables, allowing performance tuning without downtime.”

So… how much does that cost?
