Adding Concurrency to Rails Apps with Unicorn

With support for Node.js, Java, Scala and other multi-threaded languages, Heroku allows you to take full advantage of concurrent request processing and get more performance out of each dyno. Ruby should be no exception.

If you are running Ruby on Rails with Thin, or another single-threaded server, you may be seeing bottlenecks in your application. These servers only process one request at a time and can cause unnecessary queuing. Instead, you can improve performance by …

Concurrency is not Parallelism. Rob Pike at Waza 2012

In planning Waza 2013 we went back to reflect on last year’s speakers. And we want to make the talks readily available to anybody who could not make it last year—or who wants a refresher. Check back soon for more talks from Waza 2012. And we hope to see you in person at Waza 2013 coming up FAST on Feb. 28 in San Francisco.

In a world of evolving languages, frameworks and development patterns, we …

Better Queuing Metrics With Updated New Relic Add-On

Today our partner, New Relic, released an update to the Ruby New Relic agent that addresses issues brought up by our customers. The new version corrects how New Relic reports performance metrics for applications running on Heroku. Queueing time is now reported as the total time from when a request enters the router until the application starts processing it. Previous versions of New Relic only reported queueing time in the router. The new approach …

Updated Network Routing for Improved Performance

Over the past couple of years Heroku customers have occasionally reported unexplained latency on Heroku. There are many causes of latency—some of them have nothing to do with Heroku—but until this week, we failed to see a common thread among these reports. We now know that our routing and load balancing mechanism on the Bamboo and Cedar stacks created latency issues for our Rails customers, which manifested themselves in several ways, including:

  • Unexplainable, high latencies
    • …

Bamboo Routing Performance

Yesterday, one of our customers let us know about significant performance issues they have experienced on Heroku. They raised an important issue and I want to let our community know about it. In short, Ruby on Rails apps running on Bamboo have experienced a degradation in performance over the past 3 years as we have scaled.

We failed to explain how our product works. We failed to help our customers scale. We failed our community …

In between the talks, take part in an unique blend of conversation and craft through the hands-on workshops led by artisans teaching their trades from origami creations, to take-home woodblock prints, and even a hand-crafted and dyed quilt. Take part in this celebration of …

Cross-Site Request Forgery Vulnerability Resolution

On Friday January 18, security researcher Benjamin Manns notified Heroku of a security vulnerability related to our add-ons program. At a high level, the vulnerability could have resulted in disclosing our Cross-Site Request Forgery tokens (these tokens are used to prevent browser hijacking) to third parties.

We quickly addressed the vulnerability and on Sunday, we deployed a patch to remediate the issue. We also reviewed our code for related vulnerabilities and conducted a review of …

Learn from your Data with Dataclips 2.0

An organization's data is its most valuable asset. Unfortunately, that data is usually trapped inside a database with few ways to access it by a privileged handful of people. Too often reports are manually generated and their results pasted into emails; dashboards get built but rapidly become outdated and never answer the right questions.

We have so many great tools for collaborating around our source code, why is data still in the dark ages? At …
