Somebody mentioned that some research needs to be done on how a second level
cache will effect performance. Any suggestions on how to do this?
Based on observation it seems that a cache is worth it, SGI mips 4000 SC is
around 35/34 and the mips 4000 PC is around 60/58 specint/specfp.
Adding the decreased locality of Unix+X11 over dos, the higher (100 Mhz
internal) clock rate, and mips binaries being bigger then 486 it would
seem that a large secondary cache would be necessary. Based on a 486's
secondary cache being useful.
Any suggestions on how to get some numbers experimentally?
I have a decstation 3100 running Ultrix, and a 486/66 running linux
available for any attempts to quantify the advantages of second level
