Go: Profiling Inside VSCodeThu, Dec 29, 2022
Profiling Go code is a dream. If you’ve got Go installed, you already have everything you need to profile code.
Writing benchmark tests and using
pprof get me a long way in understanding
where my applications are spending their CPU time or memory resources.
There are some articles and blogs that outline how to profile Go code:
Today I learned that The VSCode Go extension has a feature built-in for running a benchmark test with a profile being recorded and then automatically opening the graphs for it right there in the IDE. This feature isn’t a necessity, but it streamlines my profiling workflow.
To profile a benchmark test, open the testing panel, right-click the benchmark, and select
Go: Test Profile.
Note: You need graphviz installed to be able to view the profile graphs. On
macOS graphviz can be installed with Homebrew and
brew install graphviz.
