I’ve a MacBook Pro Apple M2 Max 64GB RAM, running 15.4 (24E248)
I’ve this machine over a year now but recently noticed that the network latency started to increase the longer I have the machine running, example:
- I start machine on Monday morning
- between workdays I only put it into sleep / close the lid
- come Friday, the network latency is already measurable up
- I’m strictly talking about cable connection
A reboot of the machine always fixes it, so I figure it’s a “local” problem.
Example of what I mean:
$ ping 192.168.1.2 -c 3
PING 192.168.1.2 (192.168.1.2): 56 data bytes
64 bytes from 192.168.1.2: icmp_seq=0 ttl=64 time=22.275 ms
64 bytes from 192.168.1.2: icmp_seq=1 ttl=64 time=16.300 ms
64 bytes from 192.168.1.2: icmp_seq=2 ttl=64 time=10.706 ms
--- 192.168.1.2 ping statistics ---
3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 10.706/16.427/22.275/4.724 ms
But really, this shouldn’t be 10+ms. This is supposed to be sub-ms.
And it is, after I reboot the machine.
Then longer I ignore the problem, the worse it gets and then it also gets noticeable with downloads from wget/curl/Firefox/etc.
What I’m I running on the machine:
- Multiple IntelliJ products
- Firefox
- Docker
- Signal
- iTerm2
- 1Password
- and a few smaller utilities (brew, node, etc.)
I wasn’t able to reset the problem without rebooting the machine. To the best of my knowledge, Docker is the only tool I actively use which also “messes” with the network. But even shutting it down doesn’t change a thing. Nor with any of the other processes running.
I’m like 🤷 , what’s going on there?
Rebooting is an economic solution to the problem, as it usually takes days anyway until this issue becomes that noticeable.
Yet, I’m also curious as to what this could be but was fruitless so far.
