I have found that MacDiscuss exhibits poor performance when using a
Meetings file located on an AppleShare server over a slow link (i.e.
14.4Kbps). I don't know what the performance is like over LocalTalk, but I
think that it would probably be slower than necessary.
This may not be a high priority today, but may become a greater issue as we
get dialup network connectivity up and running. That is, the MIT community
will start to use more of the direct-connect network apps over .
The problem is basically that MacDiscuss seems to read/write the Meetings
file after visting each meeting. If this is true, it's unnecessary. Take as
an example the Macintosh NNTP client Newswatcher. I use this app and it
performs well under the same configuration. On startup, it reads in the
news file and keeps it memory-resident. When the user quits, it writes the
new news file. All modifications to the news file take place in memory,
resulting in better performance. Just in case you were wondering, it
doesn't keep a list of _all_ the newsgroups, just the ones to which you're
subscribed.
That's my opinion, what's yours? :-)
