Plan

Want to be involved in our next meetup on Causal Profiling (Feb 12th)? Let's have lunch and plan something cool!

Causal profiling is a benchmarking strategy that runs experiments by slowing parts of your program down until it can determine which lines would improve overall performance if improved.

Clojure doesn't have a causal profiler yet. Naively, it doesn't seem that hard! Perhaps we can divide and conquer, and present our results at the meetup.

It might be fun to plan another lunch before the meetup to check in.

Ideas:

• can existing profilers be retrofitted?
  • clj-async-profiler
  • https://github.com/taoensso/tufte
• write smallest and simplest clojure causal profiler displaying essence
• could JCoz be adapted to clojure? Profile non-Java JVM programs ByteLab-David/JCoz#23
• look into perf improvements behind https://github.com/tonsky/fast-edn
• summarize theory behind causal profiling
  • Q: is it useful for single-threaded programs?

I'm down to help plan these eventually, but I'll unfortunately be unable to make it for the next two planning sessions, if the March meetup requires one 🙁

(I'm trying to wrap up details for a Lunch n' Learn presentation I'm giving at the end of the month, then will spend the next month on implementation)

I may be able to make part of this, but have a work colleague in town.
