I have 32 nodes and for master node
it had two physical NICs and 255 VLAN interfaces for DHCP and DNS
now I’ve removed 249 VLAN interfaces and left only 6 VLAN interfaces and also
removed all those DHCP settings for 249 VLAN network segments
And this time, made cluster composed of only 5 nodes including master
Now this time, it takes like 1 min to create a container,
and 20 seconds to start it.
It’s much better now but still kinda slow though this cluster is old
Could it be problem with too many network segments?
or just many hosts -> became slow
