I am posting this article for an associate of mine that does not have access to the network. He is interested in obtaining EMACS for his VMS system and is in a quandry as to which EMACS to get; Unipress Emacs (which he and I understand is Gosling Emacs) or CCA Emacs. He is concerned about performance and has heard that Unipress Emacs outperforms CCA Emacs. Is this true? Under what load conditions? Can anyone help us with testimony based on first-hand experience? Thank you. ________________________________________ Michael E. Meyer USENET: ...!tektronix!tekcae!mikem ARPA: tekcae!mikem.tek@CSNET-RELAY USnail: TEKTRONIX, Inc P.O.

CCA emacs is known to make much more efficient use of resources than Gosling's, as well as being more true to the emacs philosophy. NOW, if only CCA would get around to sending me my copies. Every couple of weeks I call them, they apologize profusely for not having sent it yet, and say it'll be shipped the next morning. Last wednesday, the person I spoke to said they would ship it Federal Express, and that I should receive it Friday. Still it hasn't arrived. I'll give them another call this Wednesday. The reason they hadn't shipped, they said, was that they were waiting for a new shipment of manuals from the printer. However, they also stated that they would send the tape without the manuals, which they would send me later. -- Michael A.

Gee, we all use Gosling emacs here, and I must admit I haven't seen a recent version of CCA Emacs (except for talking to Z at trade shows), but the few times I did use it, I found it much more difficult to deal with (could be familiarity, of course), even though I "grew up with" DEC-20 emacs. I like the way that Gosling solved some of the human interface issues much better than the original (so much for "true to the emacs philosophy"). Also, until recently, CCA Emacs was not extensible, whereas we have (probably) thousands of lines of Mlisp code for Gosling's emacs. It seems to me that Gosling's emacs has received much more gratuitous hacking by its users than has CCA Emacs, although this seems to have decreased somewhat lately (you want features, we got features!). It is true that Gosling's emacs tends to be a slower on some operations, but this is much less true now than it was a couple of years ago. The major slowness factor still seems to be in the redisplay algorithm (a theoretically nice, but somewhat slow n**2 algorithm). Work has been done on this (I may get it installed here if I ever get the time), but I much prefer (until the load average goes up) waiting a little longer for a refresh to the DEC-20 emacs habit of redrawing half the screen because it thinks something might have changed in there somewhere (even though, at 9600 baud, it might be faster, it's less distracting to me as a user). Enough rambling. As the cliche goes, I might as well try to change someone's religion. But, to get those just trying to pick a religion ... :-) =Spencer
