    I recompiled kernel and userland (with COPTS=-mcpu=v8) on a Sparc-10
    and noticed performance improvements.

    Is there a list of what the COPTS should be for all Sparc variants,
    and all x86 variants? What is the best option for my Athlon 1700XP
    boxes, for instance?

    What I would like to hear about are the best COPTS in mk.conf for:

    x86:
    Athlon XP
    Pentium
    PII
    PII-Xeon
    PIII
    Cyrix and VIA

    Sun SPARC:
    SS10 (supersparc): use COPTS=-mcpu=v8
    Sun5 etc (microsparc)
    IPC/IPX/SS2 (to get best performance on these low-end systems)

    Can anyone point me to a reference on this?

    Cordially

    Patrick
