Reassembled packets can sometimes cause this to be over 100%. The
bytes pattern matched stat is based off of wire packet bytes. If
you're seeing 10Mbit/s wire speed and reassembling 3Mbit/s this could
make a total of 13Mbit pattern matched. Since the actual wire speed
was only 10Mbit and the statistic is calculated by taking 
bytes_pattern_matched/wire_speed_bytes which would be 13Mbit/10Mbit ==
130%

Says what percent of traffic is being pattern matched by Snort. So, if
there's traffic that is not being pattern matched this will effect the
percentage.
