These numbers are quite good. pbLUA is fast. Walt: thanks for doing
the analysis.
Now that NXT-G 1.1 is out, I wonder how fast it runs. Faster execution
performance was one of the features in this release. Perhaps someone
can do this measurement.
I reran my original test program with the current ROBOTC firmware.
It's about 10% faster than before due to some performance tuning in
the firmware. (103K cycles instead of 93K).
My original code used "sprintf" format codes to create strings for LCD
display. Many of the other alternative solutions don't support
'sprintf' and just used a generic "int to string" conversion so I
tried a modified version using this more limited functionality; this
gained another 30% faster performance.
Current ROBOTC results are:
103K with LCD display and "sprintf" formatting
134K with LCD updates and "int to string" conversion
412K without LCD updates.
