Example resource usage for the latest Memory usage -25% CPU usage - much better. |
The network observer handles an in memory buffer of application and transport level flow records and associated state that can be very large. This changes how those collections are traversed for processing. Previously the collections of flow state were copied on each reconcile loop, resulting in high CPU and memory utilization. Now each reconcile job limits itself to copying the relevant portions by using an iterator and filters. Signed-off-by: Christian Kruse <[email protected]>
