interesting database performance article

Postgres doesn't support that much compression directly. These guys decided to take the performance hit of compressing/decompressing things at the filesystem layer... but it's actually *faster*. Turns out I/O bound stuff like the database, even if you spend more CPU on compression, there are multiplicative effects if the data is smaller.
