Golang

• Memory usage can be retrieved using runtime.ReadMemStats() (Sample Gist)

• Avoid moving data to the heap for a performance improvement. When assigning variables, if you can work with the reference to your data rather than copying it out, that reduces heap usage.

  Compile your code with the -gcflags=-m look for occurrences of moved to heap. See if you can avoid that. (source, HN)
