The signature engine in BD uses more CPU cycles than it actually needs to complete the task.
Slower system performance High CPU utilization with BD
ASM provisioned and in use
For header-based signatures that appear on the top in ACY_PERF, the header exclusions can be added only on explicit headers. This should decrease the CPU usage.
Some modifications are done to the signature engine to improve performance.
