>I forked the original D1 gc and rewrote it almost entirely. I made numerous speed improvements over it, such as greatly reducing the number of pool lookups, smarter alloc/realloc algorithms, removed the 'freebits' and 'scan' bitfields from pools and rewrote the garbage collector to only use the 'mark' one, I also merged the sweep and freelist rebuild phases together to save on the overhead of yet another loop over the entire working set, also added support for the gc to free memory pools if they're entirely free.<
That looks like lot of work. Too bad we don't have a suite of GC-heavy benchmarks to test it. (Maybe Lucarella has collected something in the meantime).
Bye,
