Video: Using the Go tracer #justforfunc #profiling

What's the best way to create a Mandelbrot fractal in Go? pprof is not enough to help us with this ... let's learn how to use the Go tracer instead! 20 points posted by kenny

The Go execution tracer #profiling

Sun, 24 Dec 2017 07:25:00 +0000

Ever wondered how are your goroutines being scheduled by the go runtime? Ever tried to understand why adding concurrency to your program has not given it better performance? The go execution tracer can help answer these and other questions to help you diagnose performance issues, e.g, latency, contention and poor parallelization.

A profiling adventure to speed up go #profiling

Mon, 13 Feb 2017 13:09:00 +0000

At Ravelin, we catch fraudsters using machine learning. We extract hundreds of different signals from data that our clients send us — such as the prior fraudulence of a location, the number of devices in a customer’s graph network — in real time through our feature extraction service. We then pass these features through our trained models to produce a likelihood of fraud.

A gophercon india 2016 talk by Karthic Rao - need some help with analyzing whether algorithm A performs faster than B? Or can I know whether method A performs better than method B? Or is approach A to send JSON response to the client performs better than approach B? How to find answers for everyday performance related questions? 12 points posted by lolly

Code: Visualize call graph of your Go program using dot graphs #profiling

Wed, 04 Jan 2017 13:56:00 +0000

Intended purpose of this tool is to show overview of your code's structure by visually representing call graph and type relations. This is especially useful in larger projects where the complexity of the code rises. 8 points posted by truefurby

Benchmark storage and analysis system #profiling

Wed, 08 Mar 2017 15:37:00 +0000

We're happy to announce the launch of https://perf.golang.org/, a benchmark storage and analysis system. It provides a standard place to share benchmark results. If you make changes to any performance-sensitive code, run the Go benchmarks as you normally do. If you’re not using it already, please use benchstat instead of benchcmp to compare benchmark results. Benchstat computes statistics across multiple runs of a benchmark and determines whether differences between old and new runs are statistically significant.

When you want to publish a benchmark result (for example, when you are ready to mail a CL), run benchsave instead of benchstat (benchsave old.txt new.txt). This will upload the results and print benchstat output as well as a URL; please include both in your CL description.
