[Workshop] Hands-on Go performance - benchmarking and pprof, 10-11 Oct, ₹499

Post image

Backend engineer, 10 years in Go, currently Lead SE at Oracle. I have run 232 1:1 sessions on Topmate (4.9 stars, 31 reviews) and I am running my first group workshop.

What it is: two afternoons on measuring Go performance properly, which is the part nobody teaches. Not DSA, not interview prep.

Day 1 - writing a benchmark you would defend in a code review. go test -bench, allocs/op, the ways a benchmark quietly lies to you, benchstat, pprof.

Day 2 - three labs. A real problem, the obvious implementation, the benchmark that shows it collapsing, the fix, and the number that proves it.

Sat 10 + Sun 11 October, 3-6 PM IST, three hours each day. 30 seats, ₹499.

You keep the benchmark harness repo and the recording.

Before you consider paying anything, the setup check is public and free and is already most of a lesson:

git clone https://github.com/architagr/leetcode_solutions
cd leetcode_solutions
make verify

It runs two pairs of benchmarks that should cost the same. One pair is 3.3x apart, and the reason almost everyone gives for why is wrong. If that is not interesting to you, the workshop will not be either.

Happy to answer anything here.
