I am in the process of evaluating which option to choose for a new production deployment of a Sinatra application. Pros and Cons of the implementations: JRuby Stack: Pros: • Fast for serial execution once warmed up. • Multi-threaded, easy to scale with spiked traffic / shared resources. Cons: • Slow warm up time, app […]

There seems to be some interest Catalyst vs Rails vs Django benchmark. The older benchmark is quite old, it was done in 2007. A lot has changed since then. I am re-running the numbers once again to see what has changed. This time around the hardware is faster and the benchmark is slightly more simple. […]

I have recently blogged about swapping malloc implementations for the JVM to help boost multi-threaded performance. Well there is yet another malloc implementation that solaris comes with that is optimized for single threaded performance; bsdmalloc. I just recently switched our perl interpreter to use bsdmalloc and got 33% faster performance with our perlbal proxy. You […]

I wrote a quick micro benchmark to test out ruby threads. Apparently ruby can’t make use of multiple CPUs with it’s threading implementation. I guess you have to resort to forking to scale up to multiple cpu cores while using mri ruby. However, there is an alternative solution, just use JRuby. JRuby utilizes all cores […]
