I did some benchmarking a while ago of the port of Vassili's regex
package against the plugin, and wrote this to the list:
It did amazingly well - although it takes about 20x as long to compile
a pattern, when actually matching the plugin only gave about a 3x speed
boost. Given that either way we're talking tens of thousands of
matches per second for most input, I'm not sure a plugin is really
One advantage of using an all-Smalltalk package is that your code is
more portable; it would be a real hassle to get a PCRE plugin going on
VW or Dolphin, but Vassili's matcher already runs on them. This may
not be a concern for everyone, but it is for me.
