How to find the reason for dropped packets

pheuch

A sensor of us shows a lot of events with signature 993, reporting dropped packages. I calculated an average of 28% percent over the day. How can I find out the reason for this ?

The sensor is an IDS 4230 FE running 3.1(2)S23. What is the highest speed the sensor is able to monitor and what effect does String Matches have on the speed of the sensor?

Sorry for this bunch of questions, but it is really urgent for us to find out why the sensor is dropping packets.
