Don't describe it as "fast". Use "latency" or "throughput". RC is a useful building block for making real-time latency guarantees, and for many apps that is more important than peak throughput.
- sklogic 10y agoIt is really hard to get real time guarantees with RC - given that time for cleaning up depends on a size of a structure. Just imagine it freeing a 10Gb linked list. Real time pure mark and sweep GCs are easier.
- NickPollard 10y agoYou don't have to clean up everything at once - it's possible to put items on a queue to be cleaned up when refcounts hit zero, and you can then control at what rate the queue is emptied.
- sklogic 10y agoWhich makes it already far too complicated, more complex than a real time mark&sweep. Especially if there are loop checks - you cannot just empty the queue gradually, it's all or nothing.
