I also tested out the question i had about how bad the performance if for throwing and catching an exception, so I tested with the JMH setup and interestingly: • a

runCatching

block that doesn't throw was doing well over 200k ops/ms • a

runCatching

block that did throw and catch an exception was doing 993 ops/ms So quite the performance hit from throwing exceptions!

that is very interesting! I think that would make for a great addition to the existing benchmarks. Oh and the diagram I showed in the slides, there is this great jmh visualiser where you can take the outputted json and jsut drop it here: https://jmh.morethan.io/
