在局部变量表中32位以内的类型只占用一个slot(包括上面提到的returnAddress类型),64位的类型占用两个. byte short char在存储前被转化为int,boolean在存储前也被转化为int , 0 表示false,非0表示true,long和double则占据两个 Slot boolean占多少个字节 由上可知一个slot槽占4个字节,也就是Java中占位最小单元为4...
零拷贝指在进行数据 IO 时,数据在用户态下经历了零次 CPU 拷贝,并非不拷贝数据。通过减少数据传输过程中 内核缓冲区和用户进程缓冲区 间不必要的CPU数据拷贝 与 用户态和内核态的上下文切换次数,降低 CPU 在这两方面的开销,释放 CPU 执行其他任务,更有效的利用系统资源,提高传输效率,同时还减少了内存的占用,也提...

* Transfers bytes from `fileChannel` to this `TransportLayer`. * * This method will delegate to {@link FileChannel#transferTo(long, long, java.nio.channels.WritableByteChannel)}, * but it will unwrap the destination channel, if possible, in order to benefit from zero copy. This is required...
