I have some preliminary performance numbers for various programming languages with reference bots, I now have reference bots in 3 languages.
I also used the same data structure, and pretty much the same techniques
for each language. The Vala program is almost a direct port of the
java version (the language are VERY similar.)
My disclaimer: I am sure the performance numbers for any given platform
could be easily improved, perhaps even with different compiler options
or simple changes to code. I am no expert in any of these languages.
Below is the data as I have it now.
