How to precompile SpiderMonkey code for faster execution? -


i using code this:

js_evaluatescript(context, global,"go_back('blabla')", 17, "", 1, &r);

to call go_back(), in context. extremely slow, , think because string have compiled each time.

i try find way call same piece of code many times in fast way, without recompilation, or object creation each time. mozilla docs , sources not organized way, there reference, , need know every function before can make choice.

so hints? best practice this?

jsfunction * func = 0;  static jsbool my_native(jscontext *cx, uintn argc, jsval *vp) {     jsval r = jsval_false;     if (func == 0) {         const char *args[1] = {"s"}, *src = "go_back(s)";         func = js_compilefunction(cx, 0, 0, 1, args, src, 10, "", 0);     }     js_callfunction(cx, 0, func, 1, &r, &r);     return js_true; }

this fast (20 times in example), compared js_evaluatescript. note code simplified, still need pass string argument somehow. (i not sure myself how that.) , may need js_reportpendingexception() go_back() can fail.
