I'm not going to make a big long rattle on this question about what I've tested and number crunching. I'm more interested in actual up-to-date practice performances.
I've read tons of articles already and some of them are pretty skeptical or either very pro to one library. I'm currently testing a bit with gorp, yet I have no clue how to compare the performances of such a library towards others.
I know gorp is an extra layer that tries to add ORM to the basic SQL driver/implementation, but seeing Go's extremely clear code and being it very close to the bone on everything it does. It's not like with PHP/Python/JAVA what I'm used too, where you have to navigate through endless layers of complexity to actually see what a package does in its essence.
So my question is if anyone can share (benchmarks are always welcome :) ) their experience and knowledge on this subject.
I don't think a NoSQL-type solution is an option for my projects. All my projects always strongly depend on business logic and intertwined relationships. I also wonder if Postgres will be a win over MySQL. With Django (Python) I noticed significant performance gain using Postgres, but I never found prove on that matter if it was due to the Postgres core implementation or just Django's way of using the wrapper.
Small update
After rereading the question I noticed I kind of missed the actual goal of it. I'm actually looking for the most suitable SQL solution that will least slow down Golang itself. I know the SQL runs concurrent, but also concerning heavy traffic when running it as a web service. I won't be really bothered to drop the ORM part again if that will get me major gain on performance.
