cristian: nice work evan. it works with my tests as well.
however I am not 100% satisfied because looking conversations up is still not
as fast as it can be (this is NOT because of the patch though...)
I am testing with large tcp or sip captures (500k packets) having (very
important):
a. in case of tcp: the _same_ ip addresses and the _same_ ports
b. in case of sip: the _same_ ip addresses and the _same_ ports in the
the SDP media description
here is what I see:
1. adding new conversations is _fast_ because the frames have increasing frame
number (even though merging files may turn out to be slow)
2. looking up conversations is _slow_ because the function
conversation_lookup_hashtable() has to traverse the chain list for each and
every frame...
my proposal: cache the last found conversation; store it into the hash chain
list head (it gets 10 times faster or maybe even more). I have a patch for it.
new bug report?
