Hi all,


To the Trace Compass Scripting users: I made some benchmarks of the
various scripting engines for javascript and python and here are the
results for it: [1]

TLDR: For javascript, both available engines rhino and nashorn, have
similar performances, a bit slower than java, but that is to be expected
of course. Python is a bit less performant, though jython is predictably
ok. But py4j performs veeeerrrrry poorly when calling a lot of java
methods (like event requests!). The article explains in more details and
shows how to make awesome python scripts that use both jython (for java
calls) and py4j (for external libraries).
