TCP stream processing performance

[Kevin Wang <kevin.wang () Istuary com>]

Hello,

I am looking at Snort performance and I found that in the Preprocessor profile statistics, "s5" or "s5tcp" is taking a 
lot of time. My understanding is that s5tcp is for TCP stream reassembly and the time taking is mostly due to the 
buffering and mis-ordered packets. The actually processing by the CPU is relatively short. Is my understanding correct 
or there is other intense processing going on?

Thanks,
Kevin
