On my Mac SE, unaccelerated, under System 7.0b4, The "Speedometer" application tells me that the math processing is almost four times faster than on a stock SE under 6.0, when I have the SGIL INIT in my control panels folder. I have "Use SGIL 32 bits" selected. It would be kinda hard to compile, say, Excel with their code library, but I imagine that if Microsoft did so (fat chance) their software would speed up. The code library is only for people who are developing their own math-intensive applications. SGIL definitely makes my machine feel peppy under 7.0, and that's a feat... ;) << Brian >> | Brian S.
