Our @admin, always hard at work!

Sounds good, but what does that mean?
OK, capital letters can be environment variables, and MAX_THREADS increases performance i guess. Hmm, and concurrency is similar I think, kinda more parallel tasks or so ...

Ergo, do not answer, instead keep up w/ optimizing, haha.
We appreciate it!
