Scott) writes: Try it and watch what happens (you can artifically lower the amount of memory Mach thinks it has at boot time). When you don't have enough memory, your machine has to page from (and to) disk. When your 15 MIPS 68040 machine is page- thrashing, it's a 0 MIPS machine. If that's your idea of acceptable performance, you can save a bundle by buying a Mac Classic instead. Don't skimp! So right. We have a MIPS 6000 series computer at school with 128 megs of ram and with 72 users on it it does not swap at all and the response times are great even if the load is up to 20. That is entirely because it's not swapping. Also swapping is much faster if you can give it disc that's not used for other things.. -- Tero Nieminen Tampere University of Technology n67786@cc.tut.fi Tampere, Finland, Europe
