Hello. I have a script which defines a custom handler on mime_data event:
event mime_all_data (c: connection, length: count, data: string)
// do stuff
When this script is ran with capturing traffic in PF_RING mode using lb_procs=2, Bro processes consume 100% of both pinned CPU cores. This is not the case when capturing without PF_RING in single process mode though. What are possible reasons for this? Can it be optimized on the script side? What can be done to lower the CPU usage?
