Re: Speed kills -- 21.5 users will live a very long life.

Off by default in 21.4, on by default in 21.5, and under Mule error-checking character positions is O(n) in (point) because the internal encoding is variable-width. Also, in 21.5 we read in several megabytes of Unicode data at startup, and we also do a lot more mucking with default fonts IIRC (I think Mike Sperber reported this). According to a Ben comment, loading Unicode tables takes "a fraction of a second" on a PIII 700MHz (whatever that implies about I/O speeds). Lazy-loading is one of Ben's incomplete projects, but Non-Asian users can probably reduce that to nil, just by commenting out _never_-used character sets in lisp/unicode.el (load-unicode-tables). The font lazy-loading optimization could be put back in (unless Mike did that already). -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
