Implementing a static stack usage analysis tool - Embedded in Rust
Implementing a static stack usage analysis tool March 13, 2019 by Jorge Aparicio (This blog covers the implementation details of cargo-call-stack v0.1.2. If you are only interested in using the tool these tweets and the README will give you an idea of what it can do.) Motivation So, why would you ever want to analyze the stack usage of your program at compile time? The obvious answer is when you w
How do Ruby & Python profilers work?
Almost all of these profilers live inside your process Before we start getting into the details of these profilers there’s one really important thing – all of these profilers except pyflame run inside your Python/Ruby process. If you’re inside a Python/Ruby program you generally have pretty easy access to its stack. For example here’s a simple Python program that prints the stack of every running
Profiling and optimizing Go web applications - Artem Krylysov
Note This post was updated on 2021-04-25. Go has a powerful built-in profiler that supports CPU, memory, goroutine and block (contention) profiling. Enabling the profiler # Go provides a low-level profiling API runtime/pprof, but if you are developing a long-running service, it's more convenient to work with a high-level net/http/pprof package. All you need to enable the profiler is to import net/

Tools for profiling Rust
The first time I needed to profile a Rust application I came across Llogiq’s post - Profiling Rust applications on Linux. This post was incredibly helpful to me and succeeded in getting me off the ground. After spending a little more time with Rust and needing to do a little more profiling I’ve discovered a few alternatives that I think make valuable additions. In this post I’ll be writing about t

Profiling Python in Production - Nylas
We recently reduced CPU usage across our fleet by 80%. One key technique that made this possible was a lightweight profiling strategy that we could run in production. This post is about the ways we approached instrumentation, the tradeoffs involved, and some tools you can use to optimize your own apps (including code!). Background Nylas is a developer platform that provides APIs to integrate with

GreenletProfiler, A Fast Python Profiler For Gevent
If you use Gevent, you know it’s great for concurrency, but alas, none of the Python performance profilers work on Gevent applications. So I’m taking matters into my own hands. I’ll show you how both cProfile and Yappi stumble on programs that use greenlets, and I’ll demonstrate GreenletProfiler, my solution. cProfile Gets Confused by Greenlets I’ll write a script that spawns two greenlets, then I
