[comp.sys.sgi] Swapping performance on a 8MB 70/GT

XBR2D96D@DDATHD21.BITNET (Knobi der Rechnerschrat) (05/18/89)

Hallo,


   we have got a rather annoying problem (as we haven't got enough money
to fix it the hard(ware) way). We have an application that uses a lot of
memory (just at the moment 30MB) and is jumping back and forth in that area
(I know we should not do it, but thats the way it works). At that point the
machine is dead, paging and io-waitng all the time. Are there some system
parameters that we can try to tune in order to increase system performance,
or is the only way to either buy more memory or write a new program?

Regards

   I would say you need more memory, 8Mb is just enough to run
the system and 4Sight, without having to page.  I don't know why
SGI sells the machines with only 8Mb, it just isn't enough.  In
addition to the extra memory you could try changing the program too.
