Performance tuning, GC logs
Hi, What's the recommended way to improve my program's performance, in particular wrt garbage collection? I see jitviewer and vmprof, but I'm not sure if either is still maintained. I've noticed speed improvements after playing with the gc nursery size, but that was trial-and-error. Thanks. Albert-Jan

There is also the gc.get_stats() function might help you figure out what is going on. For more help we would need to know what exactly you mean by "speed improvements" and where you see bottlenecks in your program.
