Running a database on EC2? Your clock could be slowing you down

You can replicate out of RDS without any problems. Shoot, you can run a master in EC2 and a replica-only in RDS.

I do this presently because I have some custom stuff I do for MySQL which needs it's own EC2 instance because RDS doesn't support it.

My knowledge may be out of date now - is that with Postgres? Hopefully so.

My gripes with the performance issues still stand though. I have queries that take 30-40 seconds on RDS that complete in milliseconds on an EC2 instance which is much smaller.

That's super bizarre. Are you running MySQL with no ACID on EC2 while leaving RDS at its defaults or something?
