I have a little data processing program which makes heavy use of associative arrays, and GC almost doubles the runtime of it (~2m with GC disabled -> ~4m).

I just want to ask what's the best practice in this situation? Do I just use GC.disable and manually run GC.collect periodically?

I'd say yes.

Another option: https://github.com/economicmodeling/containers. The HashMap will give you a full control on the mem allocs.

This is a really nice library! Thanks a lot.
