Large number of PF State Lookups?
«

I am seeing what appears to be 6 times the number of state lookups compared to my PPS.
If I look at I see an average of 600-1000 PPS over the last hour.
In `pfctl -s info` I see between 5000-7000 state lookups a second.
State Table Total Rate
current entries 357
searches 21275522 5310.9/s
inserts 18675 4.7/s
removals 18318 4.6/s
Counters
match 20103 5.0/s
bad-offset 0 0.0/s
fragment 0 0.0/s
short 0 0.0/s
normalize 0 0.0/s
memory 0 0.0/s
bad-timestamp 0 0.0/s
congestion 0 0.0/s
ip-option 0 0.0/s
proto-cksum 0 0.0/s
state-mismatch 0 0.0/s
state-insert 0 0.0/s
state-limit 0 0.0/s
src-limit 0 0.0/s
synproxy 0 0.0/s
map-failed 0 0.0/s
I did tcpdump on my interfaces and I am not seeing any abnormal about of traffic (broadcasts, multicast, etc..). This appears to mainly be my Nest camera's sending video to mother google.
I expected the PPS to be close to the state lookups numbers. Am I missing something or is this normal?
