My work is mostly spent in JVM and .NET world and I am not a big fan of Go's design, so I am already biased.

However I am the first voice against ORMs in any project I work on.

If you care about performance, nothing beats tuned prepared stated going through the wire and stored procedures for heavy duty work.

In a few projects we improved batch processing times by a few hours just by throwing the ORM into the garbage can.
