Netty Poolthreadcache, 7k次。本文深入剖析Netty的内存池机制，详细介绍了PoolThreadLocalCache和PoolThreadCache的工作原理，包括它们如何缓存和管理不同大小的内存 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 See the 13 * License for the specific language governing permissions and limitations 14 * under the License. This portion of memory can reach up to 5GB. java at 4. When learning Netty, ByteBuf appears everywhere, but efficiently allocating ByteBuf is complex. 2. Netty will maintain a PoolThreadCache object for each thread. Netty project - an event-driven asynchronous network application framework - netty/buffer/src/main/java/io/netty/buffer/PoolThreadCache. netty.
