Re: [PATCH 21.4] Make syntax tables a compile time option.

Andy> You mean it gets better when font-lock is turned on? That Andy> seems weird. Sorry, I mean "if both font-lock and lookup-syntax-properties are _on_, then turning off either one gives a factor-of-5 speedup". Narrowing the buffer also helps a lot, if the buffer is already fontified. But the TraverseSchema example still takes more than 10 seconds in a no-error-checking 21-4-9-3-windows (built on Linux), hardly less than my full-error-checking 21-4-9 version. Andy> 2 seconds per character deletion is waaaaaaaay too costly. Right. I just don't have a test case available where I can see more speedup from r21-4-9-3-windows than I can get from M-: (setq lookup-syntax-properties nil). -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN My nostalgia for Icon makes me forget about any of the bad things.
