Class LogarithmicArrayByteBufferPool

  • All Implemented Interfaces:
    ByteBufferPool, Dumpable
    @Deprecated(since="2021-05-27")
public class LogarithmicArrayByteBufferPool
extends ArrayByteBufferPool
    Deprecated.
    The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.
    Extension of the ArrayByteBufferPool whose bucket sizes increase exponentially instead of linearly. Each bucket will be double the size of the previous bucket, this decreases the amounts of buckets required which can lower total memory usage if buffers are often being acquired of different sizes. However as there are fewer buckets this will also increase the contention on each bucket.
