How can I reduce my packet loss - bro version 2.6.3

Hello,

My packet loss on my workers is pretty high. I have done things like CPU pinning but its still high. Can you please assist me in how I can reduce this to under 1%. Below are some of my settings.

cat capture_loss.log - Percent lost ranges from 2.7 to about 67.69
#fields ts      ts_delta        peer    gaps    acks    percent_lost
#types  time    interval        string  count   count   double

cat node.cfg (below is the worker config in node.cfg. As you can see I pinned 23 CPUs)
[worker-1]
type=worker
host=localhost
interface=af_packet::ens2f0
lb_method=custom
#lb_method=pf_ring
lb_procs=23
pin_cpus=5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27
af_packet_fanout_id=25
af_packet_fanout_mode=AF_Packet::FANOUT_HASH

I have 32 CPUs on this server and CPU model name is - AMD Opteron(tm) Processor 6386 SE

CPU MHz:               2800.000
CPU max MHz:           2800.0000
CPU min MHz:           1400.0000

Please assist. Thanks.

Thanks,
