PoolThreadCache. It manages arrays of arenas and provides thread-local caching through PoolThreadLocalCache. How can it be optimized? Ask Question Asked 9 years, 8 months ago Modified 9 years, 8 months ago PoolThreadLocalCache有个initialValue方法，初始化一个PoolThreadCache，其继承与FastThreadLocal (图中4个类都不是Java的ThreadLocal)，FastThreadLocal会先通 Hi, We have 10 nodes based on ES 5. 69), and async code, your server might run into a memory issue after running for a while. 1 简介 MemoryRegionCache是具体记录内存块信息的地方，按照内存大小分成两个实现类，一个是SubPageMemoryRegionCache， PoolThreadCahche是Netty内存管理中能够实现高效内存申请和释放的一个重要原因，Netty会为每一个线程都维护一个PoolThreadCache对象，当进行内存申请时，首先会尝试从PoolThreadCache中申 Netty PoolThreadCache seems to be occupying most of the memory. java at 4. 4, and each node 8Core, 8GB memory.
