From: "Fabio M. Di Nitto" <fdinitto@xxxxxxxxxx> pload is a performance benchmark that measures the onwire speed of corosync. problem is that once pload has been executed, the cluster is basically dead. turn pload into a test tool, by removing corosync-pload tool and user library. cleanup pload code to make it more readable and drop lots of unnecessary stuff. add test/ploadstart tool that can configure and start pload via cmap calls.
