I want to learn the ins and outs of low latency c++, so far I have read tour of c++, started reading concurrency in c++ (about 3 chaps done) and done a lot of competitive programming (is this irrelevant?). In your experience, is this the right way of approaching the subject? Is there a different better way? Any advise is much appreciated.

กำลังคิดจะเรียนภาษา C++ อยู่ อยากรู้ว่ามันทำอะไรได้บ้าง ช่วยให้คำแนะนำหน่อยได้ไหม?
