Does that mean "for the majority of deployments, the slow version is sufficient. The few that care about performance can use Linux AIO?" I'm under the impression that the entire and only point of Linux AIO is that it's faster than POSIX AIO on Linux. > Of course, a managed environment can use Linux aio unconditionally if > knows the kernel has all the needed goodies. Does that mean "a managed environment can have some code which check the host kernel version + filesystem type holding the VM image, to conditionally enable Linux AIO?" (Since if you care about performance, which is the sole reason for using Linux AIO, you wouldn't want to enable Linux AIO on any host in your cluster where it will trash performance.) Just wondering.
