Profiling puppetmasterd with ruby-prof « mind the explanatory gap
So I’m not hugely happy with the CPU consumption of puppetmasterd under heavy load, and so I’ve been trying to work out where the bottlenecks lie. Unfortunately I’ve yet to find a smoking gun, but here’s a reasonably simple way to produce profiles of puppetmasterd. Install ruby-prof from gems. Stop any apache/mongrel/nginx instances of puppetmasterd you may have running Edit /usr/sbin/puppetmaste

How to Profile Your Rails Application – CFIS
Yesterday I mentioned that ruby-prof now supports profiling rails applications. Lets see how that works. But a word of caution before beginning. Like all web applications, Rails apps are complex. They encompass many pieces – clients on remote machines, network connections, any number of application servers and database servers. Getting the whole ensemble to work can be tricky – let alone making it
JMeter - テスト自動化ツール
The Apache JMeterâ„¢ application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance.

Apache JMeter may be used to test performance both on static and dynamic resources, Web dynamic applications. It can be u

Selenium automates browsers. That's it!What you do with that power is entirely up to you.
