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.
It didn't make any difference to indentation IIRC. Font-lock maybe.
