(int)Each connection that is opened up in Tomcat get associated with a read ByteBuffer. This attribute controls the size of this buffer. By default this read buffer is sized at8192bytes. For lower concurrency, you can increase this to buffer more data. For an extreme amount of keep alive connections, decrease this number or increase your heap size.

（int）在Tomcat中每个连接的开辟连接一个读ByteBuffer。此属性控制这个缓冲区的大小。默认情况下，这个读缓冲区大小为8192字节。对于较低的并发，你可以增加这个值以缓冲更多的数据。对于长连接数很多的情况，你需要降低这个数值或者增加堆大小。

(int)Each connection that is opened up in Tomcat get associated with a write ByteBuffer. This attribute controls the size of this buffer. By default this write buffer is sized at8192bytes. For low concurrency you can increase this to buffer more response data. For an extreme amount of keep alive connections, decrease this number or increase your heap size.

The default value here is pretty low, you should up it if you are not dealing with tens of thousands concurrent connections.

（int）在Tomcat中每个连接的开辟连接一个写ByteBuffer。此属性控制这个缓冲区的大小。默认情况下，这个写缓冲区大小为8192字节。对于较低的并发，你可以增加这个值以缓冲更多的响应数据。对于长连接数很多的情况，你需要降低这个数值或者增加堆大小。

这里的默认值是相当低的，如果面对的不是几万并发连接，你应该增大该值。

(int)The NIO connector uses a class called NioChannel that holds elements linked to a socket. To reduce garbage collection, the NIO connector caches these channel objects. This value specifies the size of this cache. The default value is500, and represents that the cache will hold 500 NioChannel objects. Other values are-1for unlimited cache and0for no cache.

（int）NIO连接器使用NioChannel这个类来持有链接到一个套接字的元素。为了减少垃圾收集，NIO连接器缓存这些通道的对象。此值指定这个缓存的大小。默认值是500，表示缓存将持有500个 NioChannel的对象。-1表示不限制缓存大小，0表示不缓存。
