Go is all about parallelism and concurrency, but they don’t come for free. This talk is about measuring their contention price, and being able to reduce it.

Some light will be shed on ways to measure the computational power wasted waiting. The trace/block and pprof tools and libraries will be explained with actionable examples.

After showing how to find contention issues, some handy ways to address them will be shown: -Splitting work: different ways to change common algorithms to not have a …
