Snort 3.0 does process packets differently than Snort 2.X and you will 
better performance for equivalent configurations.  To get more 
performance, use hyperscan.  And to get best performance, use service 
rules like alert http (not yet available from Talos).

As far as we know, the new http_inspect works very well and is a huge 
improvement over the old one.  Of course, it is a major new piece of 
code and we are actively working to improve it.  If you are aware of any 
issues, please send the details to bugs at ...2256...
