Python Profilers

BY Dinesh Surapuraju

Python performance measurement tools help us to identify performance bottlenecks in our app. This allows us to focus on the business login as opposed to writing custom code, setting it up with our app, and then figuring out whether the results are accurate enough. These tools are well tested by the open source community and used by many companies to measure the performance of their web apps.

Birds of a Fiber: A look at Falcon, a modern asynchronous web server for Ruby

BY Derek Haynes

What is Falcon? The GitHub Readme describes Falcon as, "... *a multi-process, multi-fiber rack-compatible HTTP server ... Each request is executed within a lightweight fiber and can block on up-stream requests without stalling the entire server process."* The gist: Falcon aims to increase throughput of web applications by using Ruby’s Fibers to be able to continue serving requests while other requests are waiting on IO (ActiveRecord queries, network requests, file read/write, etc).

Benchmarking Ruby Code

BY Matthew Chigira

One of the joys of using the Ruby language is the many different ways that you can solve the same problem, it’s a very expressive language with a rich set of libraries. But how do we know which is the best, most efficient, use of the language? When we are talking about algorithms which are critical to the performance of your application, understanding the most efficient approach to take is essential. Perhaps you’ve been using Scout to hunt down issues, and now that you have found an issue, you want to optimize it. Ruby’s Benchmark module provides a very handy way for you to compare and contrast possible optimizations, and when used in conjunction with a good APM solution it will ensure that you have all bases covered. Let’s take a look at how you can get started with it today!
