[Oisf-users] Order of matching criteria in rules

Hi

There is an interesting part on the snort site about the order of
matching criteria:
http://manual.snort.org/node36.html#SECTION00494000000000000000

Basically it says that "discrete" criteria (dsize, flags, flow, ...)
should be placed in front of "content" criteria for performance
reasons.

Does this apply to Suricata as well? Or is there some fundamental
difference in the matching algorithms ?

Erich
