Hey, I only just got Internet connected .. at present I can't run my comp on boat power (need shore power from a marina). That's being fixed at the moment (2,5Kw inverter, 4 extra solar panels, and 3 extra batteries). Been learning to grind and paint, repair plumbing, wire electrics, diesel engines, nicking chart plotting software, navigation, weather, radio operation .. and of course sailing. Er .. so I've had my hands full "moving house".. :) > We can actually generate > faster than g++ code, even though we compile down to c++ and use g++ > as our backend :) I guess we just generate code thats easier to > optimize. Last I heard, though, our garbage collected stuff can be a > little slow. Does anyone know the status of it? The GC is a naive mark and sweep. It's precise over Felix allocated objects, and conservative over the stack. It uses an ultra fast lookup (Judy array), and should outperform the Boehm collector BUT it doesn't track malloc'ed objects. The tuning mechanism is primitive. For C like programs the GC is not used so there is only a small overhead. Unlike functional languages Felix tends to allocate a small number of large objects, so the lower per object performance isn't quite as serious as you might think. Unfortunately, a copying collector would be faster but they're not really compatible with arbitrary C/C++ codes. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
