any database performance test for rails?

hey guys,

Our company use Asterisk and MS SQL for an IVR application. Our
application is based heavly on MS SQL. But we want to change to a
linux server with Asterisk+RAGI (rails AGI)and a database but I dont
know whether mySQL or postgreSQL is better for performance for rails?

Are there any tests done to compate rails+mysql and rails+postgresql ?

Thanks

Performance is more determined by what you are doing. The difference is speed is probably negligible compared to doing optimizations in your own app as both are used in high-availability/high-performance sites. Use what makes sense for you development environment. Either will performance nicely.

Yes, there are quite a few, not too hard to search for. you didn't
say anything about requirements, if you're running exclusively in AR,
or doing a little connection.execute(), or using smarter DBMS, PSQL,
triggers, procedures, etc.
