Every 10th packet to localhost has high latency on SG-2440
-
Hi,
I have been debugging latency problems on my network and ended up narrowing it down to the SG-2440 running community version of pfsense. When I login to the machine and issue a ping localhost command I get:
root: ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.093 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.048 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.052 ms 64 bytes from 127.0.0.1: icmp_seq=3 ttl=64 time=0.055 ms 64 bytes from 127.0.0.1: icmp_seq=4 ttl=64 time=0.046 ms 64 bytes from 127.0.0.1: icmp_seq=5 ttl=64 time=0.059 ms 64 bytes from 127.0.0.1: icmp_seq=6 ttl=64 time=0.061 ms 64 bytes from 127.0.0.1: icmp_seq=7 ttl=64 time=140.970 ms 64 bytes from 127.0.0.1: icmp_seq=8 ttl=64 time=0.061 ms 64 bytes from 127.0.0.1: icmp_seq=9 ttl=64 time=0.068 ms 64 bytes from 127.0.0.1: icmp_seq=10 ttl=64 time=0.068 ms 64 bytes from 127.0.0.1: icmp_seq=11 ttl=64 time=0.040 ms 64 bytes from 127.0.0.1: icmp_seq=12 ttl=64 time=0.057 ms 64 bytes from 127.0.0.1: icmp_seq=13 ttl=64 time=0.057 ms 64 bytes from 127.0.0.1: icmp_seq=14 ttl=64 time=0.063 ms 64 bytes from 127.0.0.1: icmp_seq=15 ttl=64 time=0.060 ms 64 bytes from 127.0.0.1: icmp_seq=16 ttl=64 time=0.066 ms 64 bytes from 127.0.0.1: icmp_seq=17 ttl=64 time=146.021 ms 64 bytes from 127.0.0.1: icmp_seq=18 ttl=64 time=0.056 ms 64 bytes from 127.0.0.1: icmp_seq=19 ttl=64 time=0.046 ms 64 bytes from 127.0.0.1: icmp_seq=20 ttl=64 time=0.052 ms 64 bytes from 127.0.0.1: icmp_seq=21 ttl=64 time=0.058 msso every 10th or so packet has >100ms ping time. This also for packets going through the firewall or hitting the firewall from a remote host.
Any leads what I should look for here?
best,

HA! Sorry to bug you all. I spent some more time in this forum and discovered the Netgate Coreboot Upgrade package. I applied an update and that seems to have done the job. Ping times are find now. VoIP sounds good, too!
