Hm, these numbers (richards and regexp in particular) suggest both JITs are
enabled or they'd be even worse... Can you try this silly micro-benchmark
and see what numbers you get, shell vs embedding?
(function() { var t = new Date; for (var i=0; i<2000000000; i++) {};
print(new Date - t); })();
Also check you're using the same CompileOptions, Evaluate/Compile JSAPI
functions (also for your load() function) and the same GC settings (max
bytes, nursery bytes, JS_SetGCParameter calls).
