Will It Optimize?
See how well you know (or can anticipate) gcc's optimizer. For each question, the left box contains some code, while the right box contains code that purports to do the same thing, but that illustrates a particular optimization. Will gcc apply that optimization? Put another way, will the code on the left be as fast as the code on the right, when compiled with an optimizing gcc? I used a pretty anc
haypo / astoptimizer — Bitbucket
Clone in SourceTree SourceTree is a free Mac client by Atlassian for Git, Mercurial and Subversion. AST Optimizer astoptimizer is an optimizer for Python code working on the Abstract Syntax Tree (AST, high-level representration). It does as much work as possible at compile time. The compiler is static, it is not a just-in-time (JIT) compiler, and so don't expect better performances than psyco or P
Optimizing Real World Go
05 January 2013 This is about some fun I had while putting together a small Unix-y utility to measure RAM and swap usage - psm. I was able to decrease runtime by more than 65% during a 3-hour train ride with the help of some standard go tools. Background At my place of employment we’ve had memory-usage problems over the past month, following a restructuring in how we distribute long-running jobs b
Constant and Global Optimization in JRuby 1.7.1 and 1.7.2
Charles Oliver Nutter Java, Ruby, and JVM guy trying to make sense of it all With every JRuby release, there's always at least a handful of optimizations. They range from tiny improvements in the compiler to perf-aware rewrites of core class methods, but they're almost always driven by real-world cases. In JRuby 1.7.1 and 1.7.2, I made several improvements to the performance of Ruby constants and
