Of course this depends on the length of your string, and to some extent to
its contents, but generally RegEx's are pretty fast. (Faster than
String.IndexOf, for example).

I'd guess the network would be the main bottleneck in the application you
describe, but if matching performance is as critical as you say, I'd suggest
to perform benchmarks of the following alternatives:
- a "bare-hand" Boyer-Moore implementation
- C/C++'s strstr function (uses CPU-specific optimizations)
- RegEx.Match
using real test data.

Post your results, if you're done!
