May 22, 2001 - On news://news.scitechsoft.com/beta.scitech.display.doctor.os2 I found this tip from Erik Overby on how
to perk up the video performance on an SMP system under OS/2-eCS. Since I have 4 SMP machines (three running WSeB and
one running eCS Pro), this was of particular interest to me personally:

    I posted a message yesterday about poor graphics performance with SDD on SMP systems, DIVE in particular. I was
    talking a bit to Markus yesterday, and he said the problem is that one cannot set the MTRR's for both cpu's on a
    SMP system. In particular, what one would want to do is to enable write-combining for both/all CPU's. However I
    thought that hey, this has to be possible, because afaik they do on Linux.. And rightly enough; there is a
    utility on hobbes (p6k7mtrr_v006.zip) that lets you set the MTRR's for Pentium (I/II/III/Celeron etc.) and
    K7 (Athlon/Duron/etc) CPU's from Ring3, through a special device driver. The utility has in it's latest
    versions got a -m parameter, which makes it try to set the MTRR's for _all_ cpu's in a SMP system.

    And trust me on this: It works. DIVE performance is like quadrupled, and the system otherwise seems snappier
    aswell, especially Netscape. Not to mention that the problems I've had in the past with messed-up sound in
    FLASH animations are now gone (and FLASH performance is _much_ better).. This is like getting a new computer!

    So.. Have a look at this, all you SMP people.. And for you, Scitech, maybe this is a (not _the_) way to go?

    Best regards,
    Eirik Overby

    Btw, I noticed that in the WarpMedia FAQ/Readme they mention this too; but afaik they had no idea it would
    be so effective on SMP systems ;)
