Design and Implementation of a High‑Concurrency Memory Pool in C++

This article presents a comprehensive design and implementation of a high‑concurrency memory pool in C++, covering concepts such as fixed‑size block allocation, thread‑local caches, central and page caches, lock‑free techniques, span management, and performance benchmarking against standard malloc.

Root Cause Analysis and Optimization of Long Young GC Times in gRPC/Netty Services

Long Young GC pauses in gRPC/Netty services were traced to Netty’s default thread‑local cache creating many MpscArrayQueue objects, and disabling the cache with the JVM options ‑Dio.netty.allocator.useCacheForAllThreads=false and ‑Dio.grpc.netty.shaded.io.netty.allocator.useCacheForAllThreads=false reduced GC time from up to 900 ms to about 100 ms, stabilizing the service.
