Hi there- I'm considering adding more memory to my NeXT--either 4meg or 8meg. I'm wondering how much of a performance increase I'll get with either upgrade--is it very noticeable? I notice that I spend a decent amount of time doing context swaps since I jump around a lot and have a lot of stuff open. What are people's experiences? Also, where are some good places to get memory nowadays? A few months ago there were some suggestions, but I'm wondering what the current situation is. thanks, -Avery Wang awang@isl.stanford.edu

You should absolutely, difinitely, positively get more memory. How much depends on what you're doing. You will notice a rather considerable difference going from 8MB to 12MB almost no matter what you do. If you tend to do only relatively modest things (i.e. you don't act as a print server for anybody else, you don't run the Sybase server for anybody else, you don't keep too many things like TopDraw and Frame shuffling back and forth), 12MB will be all you need. If you do any of the above, however, go for 16MB. I've never experienced a cofiguration with >16MB, but in our use the server machines with 16MB feel about the same as the 12MB clients. (We haven't done any measurements, so we don't really know which is better.) Just go to any mail-order source for fast SIMMs. They seem to all work fine. Good luck, Denis Lynch ESL, Inc.

It's painfully obvious how much having enough memory impacts performance, especially when dealing with Mathematica or Common Lisp. A 25MHz 68030 goes a long way when it doesn't have to service page faults. The 68040 upgrade + 40MB RAM + 330MB "swap disk" should be a good configuration for a serious client workstation. (And it could record or play a whole 3 minutes of digital audio!) Anything less than 16MB is just plain stupid. -=EPS=-

As far as I have heard, 16 Mb is still the limit for the machine.
