- CyberDildonics 6y agoThere is no such thing as "memory consumption". There is memory bandwidth and memory latency. If something is CPU bound it is likely to be memory latency unless it is very optimized and running on multiple cores. If something is not CPU bound neither memory latency or memory bandwidth will be the current bottleneck because both show up as CPU time.
- seedless-sensat 6y agoI think the parent comment was suggesting a common scaling limit for web severs is that inflight requests exhaust the host's memory capacity.
- CyberDildonics 6y agoI don't think I have even seen memory use be a benchmark for server frameworks. When is that ever actually a problem? Wouldn't that mean hundreds of thousands of in flight requests?
