Ah, Thank you. So this is my problem. I use
should solve this.
It's weird that this issue didn't come up earlier on that cluster, but
after killing fstrim all problems we resolved and the cluster ran
happily again.
So watch out for fstrim on early Sunday mornings on Ubuntu!

Hi,
Last sunday I got a call early in the morning that a Ceph cluster was
having some issues. Slow requests and OSDs marking each other down.
Since this is a 100% SSD cluster I was a bit confused

IFNAME should you provide that.
Yes, I tested that as well. But I have to add, the other deployments I
tested all run with the default settings and do get a good latency.
But I turned off lro for example, that didn't help either.

Indeed, there must be something! But I can't figure it out yet. Same
controllers, tried the same OS, direct cables, but the latency is 40%
higher.
perhaps something with pci-e
. But a basic ICMP test on a idle machine should
be a baseline from where you can start with further diagnosing network
latency using better tools like netperf.

Hello,
While working at a customer I've ran into a 10GbE latency which

on all these networks and cards.
I was wondering, others with a Ceph cluster running on 10GbE, could you
perform a simple network latency test like this? I'd like to compare the
results.

No, they don't seem high, but they are about 40% higher then the values
I see on other environments. 40% is a lot.
This Ceph cluster is SSD-only, so the lower the latency, the more IOps
the system can do.

somewhere, but I can't think

The systems I have access to have no special tuning and get much better
