Over on comp.os.linux.development.system someone asked an interesting
question, and I thought I'd mention it here.
Given a fast low-latency solid state drive, would it ever be beneficial
to simply wait in the kernel for synchronous read/write calls to
complete? The idea is that you could avoid at least two task context
switches, and if the data access can be completed at less cost than
those context switches it could be an overall win.
Has anyone played with this concept?
I don't think most SSDs are fast enough that it would really be worth
avoiding the context switch for.. I could be wrong though.
