I've got the code in the
benchmarksdirectory that I've been using - they're not perfect though.Are you compiling with
RELEASE=1? Without it, the asserts are left in which really kills performance.The stuff marked
ALWAYS_INLINEis worth going for first. SpecificallyjsvGetAddressOfLock,UnLock,Ref,UnRef,Get/SetXXXChild/Siblingare all very small functions with big improvements from inlining (in fact they shouldn't increase code size much at all).Same for
jsvIsXXX- in fact by inlining those, the compiler should be able to remove some of the null checks.Perhaps you could look at having two inline defines,
ALWAYS_INLINEandMAYBE_INLINEor something?Espruino itself really isn't that fast though - or does ESP8266 look bad in comparison with other STM32 based boards?
