I was wondering if someone could point me in the right direction for
I'm finding it hard to get a definition of what constitutes IOWait.
I know that IOwait is CPU time waiting for IO to happen to physical
local disks, but I'm unsure about the following scenarios and if they
contribute to IOWait:
- CPU time waiting for an NFS read/write to occur
- CPU time waiting for a network buffer to be read/written to. eg
waiting for a full buffer to clear.
- Anything else??
PS. How do you set/query the network buffers in Linux?
