The number of traps that are processed and specified in trap_mgr.conf is a factor in performance. The smaller the number of received traps processed as events, the higher the overall rate of processing.
With trap receiver you can import subsets of traps into the Adapter Platform. Large numbers of traps may be sent by network devices, but typically only a small subset are important to network operators. For example, link up and down traps are sent frequently by devices but are not typically important to display to the network operator since the IP Availability Manager already supplies authentic, root-cause problems related to these traps.
