LuaTeX knows how to not embed fonts if you ask it not to, but I'm not sure how this is handled on the ConTeXt level.
but it runs really slow on my ancient PC, especially on the first time when it's generating font cache.
That's true, it needs a lot of memory (so most of the time is spent swapping, I guess). As I've found out, Mark IV is slightly faster on a 450 MHz Sparc processor with 1GB memory than on a 2GHz Intel Dual Core with 512MB memory ;-)
This is especially true if you use large fonts like the AdobeMingStd. It should slowly be getting better over time, Hans and I hope. We try to optimize for memory use as well as directly for speed, because less memory is often faster also. However, premature size optimizations tend to cause problems later on, and therefore progress is slow. Best wishes, Taco
