Hi,

I compared the following two in JSC and in v8:

A: result = str.match(regex);

B: while (regex.exec(str)) ++count;

str was about 20M input, and regex was /./gm

JSC:
A: 618 ms
B: 3469 ms

V8:
A: 2640 ms
B: 1833 ms

I was quite surprised that although the result is a really huge array,
str.match was much faster in JSC. Is there a known reason to that? Can B
be improved in JSC?

Regards,
Zoltan
