---------------------------------------
Summary: Improve performance of ChannelDataInput.readBits(int)
Key: SIS-306
URL: https://issues.apache.org/jira/browse/SIS-306
Project: Spatial Information Systems
Issue Type: Improvement
Components: Storage
Affects Versions: 0.6, 0.5, 0.4, 0.3
Reporter: Martin Desruisseaux
Priority: Minor
Profiling shows that reading of compressed file formats spend a lot of time in
{{ChannelDataInput.readBits(int)}}. We may try to improve performance by
replacing all calls to {{readByte()}} and {{readUnsignedByte()}} is that method
by calls to {{buffer.get()}}. But before, we need to invoke
{{ensureBufferContains(int)}}. However we will try to invoke the later method
only once, instead than at each call of {{readByte()}}.
