    I STRONGLY second that motion for lmbench:  it is an outstanding
    microbenchmark for measuring the cost of core OS system calls and
    services:  context switch, process creation, networking, and IPC.  Linus
    strongly respects lmbench results, so its important for us to use this
    Kernel compiles are a fairly good macrobenchmark.  It is not exactly a
    typical server workload, unless your server is a compile server :-) but it
    pretty heavily exercises the machine, and it's easy to run frequently,
    because kernel hackers have to run it frequently anyway :-)
