What is the scale of cluster usage supported by Flannel ?

[busishe]

My cluster use flannel to allocate subnets.Now there are 127 nodes in the cluster，everything running good.I'm not sure if there will be performance issues when my cluster gets bigger

I only know a bottleneck when you try to deploy too many pods in a single node: there is a hard-coded limit you can connect to a Linux network bridge. I am also curious about the design scale of flannel.

Which type of network backend your flannel is using，Performance issues may be minor in host gateway mode。

Yes.it's hard to reach the limit of a single node in daily use

I use vxlan mode.My cluster nodes are in three subnets.
