What should a developer do if suddenly one day they get assigned to debug a Sev1 performance issue?
From our experience, sometimes finding the problem itself is very difficult and thus takes a lot of time. In this talk we will talk about some profilers which one can use to get visibility into what’s happening while executing code. These profilers may not always give us the exact root-cause but will always be able to give us directions to debug further.
To also make things more relatable, as a case-study, we would be using a real problem which our team dealt with recently while upgrading the Ruby version of one of the largest monolith Rails application.
