1. Obviously, branch prediction, as mentioned above. 3% speedup for (almost) free is nothing to sneeze at.
2. Profiling bro to identify other hot spots that could benefit from optimization.
3. Best practices for compiling Bro (compiler options, etc.)
4. Data structure revisit (hash functions, perhaps?)
Jon Siwek was optimizing the main event loop last February, but I believe it could only go so far without the new Broker API being integrated. Also, I believe there is a need to move off of the select() function. Anyway, there is definitely a lot of optimization that could be made there.
