- We have a mixed environment of SUNs and X-terminals (NCDs). The heuristics
- we use are that a power-user (one who uses Lisp-based applications, does
- simulation-work, etc) gets a Sparc-ELC. 'Normal' users get an X-terminal.
- We have a number of Sparc-2s with 32 MB RAM and 128 MB swap. Each SS-2
- serves about 6 X-terminals. This situation is workable (our bottleneck
- is our fileserver, not the SS-2s). I looked into the same question when
- we started and concluded that you should use at least SS-2s (or better)
- to serve the X-terminals. The smaller machines (like the ELC) can serve
- maybe 2 or 3 X-terminals (the SS-2 is much better, because of better
- hardware support, eg. for context-switching). I'm looking into the
- new SS-10s. I hope I one of those can serve 20 - 30 X-terminals.

- PS. There is also the question of how many X-terminals you can put
- on one ethernet. You might find that a few dozen X-terminals will
- swamp your ethernet. ('xlock' is a notoriously example of this)
