If you don't have personal examples of using a profiler to diagnose an issue like "too many round trips" and identify where those round trips are coming from, then you've never inherited a complex performance problem before.
replyDoesn't really change the picture. If you don't know the basics of a car, then you absolutely shouldn't be driving in traffic either.
replyyeah but that analogy is sort of false. A better analogy...but then it would make you look absurd...would be "if you don't know how to take apart and re-assemble the engine of a vehicle you shouldn't be allowed to drive it on the road". You get a driver's license if you can remember a few common sense facts and spend a bit of monitored time behind the wheel without doing anything absurdly illegal or injuring/killing somebody
replyYou don't use like Datadog or something at your enterprise job?
replyThat is surprising. They have come up in every enterprise job i have had. Debuggers and profilers absolutely do help although for distributed systems they are called something else.
