Re: Why Uber Engineering Switched from Postgres to MySQL
The article talks about Postgres mostly delegating caching to the OS while dealing with it via system calls (which they describe as "expensive"), while InnoDB has its own implementation and is therefore faster.<p>I wonder if part of the problem is really Linux, not Postgres and that another way they could have addressed this is by trying FreeBSD (which is what a lot of people run Postgres on).
