I show 180-350µs between various machines on my network, all of which have some fiber between them. devices with only a switch and copper between them somehow perform worse, but this is anecdotal because i'm not running something like smokeping!
Oh, additionally between VMs i'm getting 180µs, so that looks to be my lower bound, for whatever reason. my main switches are very old, so maybe that's why.
- jeffbee 5y agoAre you measuring that with something like ICMP ping? I think the way to gauge the actual network speed is to look at the all-time minimum RTT on a long-established TCP socket. The Linux kernel maintains this stat for normal TCP connections.
- genewitch 5y agoYes, ICMP ping. I don't have any long established sockets anyhow so i don't know how useful my set of those stats would be.
