In Kubernetes deployments, you can specify volume mounts as readonly. Is there a performance advantage to it, or logical only?
Is it dependant on the volume type?
To make my intentions clear, I'm using a pv in a scenario where I have one writer and many readers, and noticed any fs operation on the mounted volume is much slower than on the volatile disk.
It entirely depends on the volume type. Some might implement performance optimizations when they know the volume is read only.
