I don’t think there’s too many of us on the ‘GC did nothing wrong’ hill.
replyReading the average HN opinion, it seems everybody is writing high-performance latency-sensitive systems that would implode if a response would take 1 ms longer than normal.
Sampling bias. Most of the people responding are probably those with a strong opinion because of what they work on. Everyone else is likely relatively indifferent to it.
replyIt is a misconception that GCs only affect latency-sensitive systems. High-performance throughput-optimized systems are also sensitive at ~1µs granularity for different reasons, so GCs are not used there either.
That a GC is adverse to the performance both latency-oriented and throughput-oriented workloads doesn't leave many use cases in "high-performance" systems. Maybe systems that are severely I/O bound but is barely a thing these days.
