Hi Charles, Very interesting data. This inspired me to run some benchmarks. It may not be directly relevant but I thought you might like to see this data. I just ran your benchmark [ fib(25) ruby code is interpreted 'uncompiled' on 0.9.0]. I compared against an equivalent fib function in each of the dynamic languages that we have available on NetKernel. Since last week's 0.9.0 that includes JRuby! Here's the results:
<times> <test><lang>beanshell</lang><time>5.308</time></test> <test><lang>groovy</lang><time>3.081</time></test> <test><lang>javascript</lang><time>0.185</time></test> <test><lang>python</lang><time>0.402</time></test> <test><lang>ruby</lang><time>18.657</time></test> <test><lang>java</lang><time>0.001</time></test> </times> Not inferring any great significance from this data since the results are on 0.9.0 without any of your recent optimization work. For background, the way our script engine works is to dynamically compile/pre-parse scripts to the most optimal form we can manage in each language. The optimization breakdown by language is: beanshell v1.3: pre-parsed interpreted groovy jsr6: compiled bytecode javascript rhino 1.6: compiled bytecode jython: compiled bytecode jruby 0.9.0: interpreted NetKernel has dependency caching so we 'optimize' and then cache scripts and only rebuild if the script is edited. It would be really great if as part of the JRuby optimizations that there was an interface that allowed us to build pre-parsed AST for caching. Having become very familiar with embedding dynamic languages I'd say that Rhino has the cleanest separation between compilation and execution phases - the API allows you to run a compilation phase that pulls in dependent scripts. Each execution of the compiled form can be passed an execution context with passed in local variables etc. Worth taking a look at for ideas. FYI we integrated JRuby 0.9.0 last week. Its working great and complements the existing choices we offer. We haven't issued a public release yet but I know some of our customers are excited about the possibility of using Ruby on NetKernel. A big thanks to you all for your great work! I have some other ideas with regard to embedding - we had to override some of your classes to get what we needed. I'll post the details in a separate thread (later in the week time-permitting). Hope this data helps give a relative perspective across the current embedded language scene. Not sure we can offer the depth of knowledge to help with the detailed optimization but if you need a relative test of a stable build just ask. Thanks again, Peter PS If anyone wants to play with these tests just let me know and I'll send the NetKernel script library unit test module and our ext-script module with JRuby embedded.
