Re: Need help to decide Mysql vs Postgres

Hi Josh,

Thanks for the prompt reply !! Actually migration is inevitable. We have a
totally messed up schema, not normalized and stuff like that. So the goal of
the migration is to get a new and better normalized schema. That part is
done already. Now the decision point is, should we go with postgres or
mysql.

Thanks,
Amit

It is my experience that MySQL is faster under smaller load scenarios.
Say 5 - 10 connections only doing simple SELECTS. E.g; a dymanic website.

It is also my experience that PostgreSQL is faster and more stable under
consistent and heavy load. I have customers you regularly are using up
to 500 connections.

Note that alot of this depends on how your database is designed. Foreign
keys slow things down.

I think it would be important for you to look at your overall goal of
migration. MySQL is really not a bad product "IF" you are willing to
work within its limitations.

PostgreSQL is a real RDMS, it is like Oracle or DB2 and comes with a
comparable feature set. Only you can decide if that is what you need.
