History: Lojban MOO Performance

Source of version: 3 (current)

mooix is not terribly high-performance, and the machine it's currently running on is fully encrypted, which Doesn't Help (tm). Here are some notes and ideas about how to make things better: ! Improvement Suggestions Faster hybrid daddy: have markers like Eimi's untagged special in the main source tree; users can insert them themselves if they want, but they don't have too, but not having to go all they way up the tree saves time. session, $avatar, $direct_object and $this flags (and any similar things that may exist) are not shortcutted in msg.c; that is, propigate is run all the way through, even though (presumably) finding the targets for a message with those flags requires no propigation. I suspect this to be fairly serious. Performance suggestion: Per-user flag to select from the following: 1. Daddy Tag 2. Own language always. 3. Daddy Tag with own language. #2 being much, much cheaper. There must be *something* that can be done to make nearbyobjs faster. Caching it and watching for changes is one possibility; test mod time on the location's contents? Enh. Rather larger scale idea: We could have a layer in the language bindings that caches results for 1 second (unless told not to). Dunno if this would be faster than a RAM disk on a real box. Might be better done on the parser; probably the most savings there. ! Benchmarking Results All these are from "look" in Robin's MUD Workshop by m-test (i.e. an English user).
