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

On the one example I have where there's a gross difference between your patch and vanilla 21.4.9, disabling lookup-syntax-properties gives me about a 4:1 speedup in a --with-syntax-text-properties build (in a r21-4-9-3-windows tree with no debugging or error-checking). There's no subjectively perceptible difference with the default build. This is also the case for my usual build (nearly vanilla 21.4.9 --debug --error-checking=all --use-union-type), except that all times are about 40% longer. The 4:1 ratio for lookup-syntax-properties t vs nil holds, though. I thought you said setting lookup-syntax-properties nil didn't help? -- 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.
