WebThe Netty 4.1 ByteBuf would automatically expand in capacity as needed when written to, until a certain maximum capacity. The new Buffer API no longer do this, and no longer have a capacity and max-capacity distinction. Code should instead allocate properly sized buffers (the size argument is now mandatory), and/or call ensureWritable () as needed. WebApr 3, 2024 · ByteBuf is not an interface but an abstract class According to our internal performance test, converting ByteBuf from an interface to an abstract class improved the overall throughput around 5%. Most buffers are dynamic with maximum capacity In 3.x, buffers were fixed or dynamic.
