kubectl exec is very slow on startup and while doing interactive work is nearly unusable

[ludat]

I'm pretty sure this used to work fine and I'm not sure when it started performing poorly but right now running

$ time kubectl exec -ti argocd-application-controller-0 -- pwd
/home/argocd
kubectl exec -ti argocd-application-controller-0 -- pwd  0,08s user 0,05s system 0% cpu 27,642 total

so 30segs for just pwd, which doesn't make much sense, I'd expect a couple of seconds.

And running kubectl exec ... bash is nearly unusable, it works but is very very slow.

We are debugging issues with some control planes where the performance is degraded. And your control plane might also be affected. Refer: https://status.spot.rackspace.com/status/uptime. We will get back to you once that is resolved.

Thanks, I just tested and perf improved quite a bit: now it takes 3secs.

If you are ok with it I'll close this.

sure thing. We are still working on some performance optimizations, we will keep everyone posted in the status page.
