    for N CPU's = % avg CPU / process= 1/N x100% Why? RPC throttle or what?

    Examples are MS Office, WordPerfect(Qpro 2020), LibreOffice and ProcExp, Procmon all having this 1/N x 100% for N CPU limit utilization. This reminds me of my 3rd employer Burrough's as Test Eng. Mgr when I heard all Mainframes had full speed but marketting sold keys to clients too CPU...
