Hello, everybody, I'd like to thank the people who responded to my earlier
query about unuseable performance of OpenWindows on a 3/80. You all said
it was a memory problem. While I agree that it could certainly use more
memory, this alone does not explain the poor response (except see below).
All of our 3/60's and several of our SPARCstations (including my own) also
have only 8MB of main memory, and they are all performing quite acceptably
with more windows open than the fellow on the 3/80 has. Additionally, the
3/80 is monochrome while the 3/60's are all colour, so if anything it should
be less affected.
The only difference I can think of is that the 3/80 is at 4.0.3, while the
rest are at 4.1. However, before the other systems were upgraded to 4.1 last
summer, they had been running OpenWindows for a few months, and nothing
like this was observed on them when they also were at 4.0.3. Perhaps there is
something in the 3/80's architecture or MMU that means it *requires* more
memory than the others to run equally well?
