On: V8 performance can beat C sometimes

[anjanb]

why is golang so much slower compared to Java ? Is it because the language is immature or because the language libraries are immature ?

[chimeracoder → anjanb]

Go not only uses a different library for processing regular expressions, but a different algorithm altogether. It is slower in some cases than the standard PCRE implementations but faster in others.
