      After investigating performance degradation wrt eBPF Agent CPU usage, we found very aggressive GC calls happening in stressed environment (sampling=1 + load injection)

       

      We want to compare performances from two potential fixes:

      1. Turning off forced GC by default (https://github.com/netobserv/netobserv-ebpf-agent/pull/184/ )
      2. Removing forced GC specifically on the ringbuf tracer ( https://github.com/netobserv/netobserv-ebpf-agent/pull/185 )

      Note that 1. can also be achieved by setting in FlowCollector CR under the ebpf section, using the current 1.4 candidate build:

            debug:
              env:
                ENABLE_GARBAGE_COLLECTION: "false"
