------------------------------
Summary: Improve tailer's reading performance
Key: IO-332
URL: https://issues.apache.org/jira/browse/IO-332
Project: Commons IO
Issue Type: Improvement
Reporter: Liyin Liang
Now, Tailer triggers a lot of calls to the underlying runtime system, that is,
RandomAccessFile.read(), a native method that returns the next byte of the
file. This approach is too slow to meet our need. The performance can be
improved by using a large buffer, that is using RandomAccessFile.read(byte[]).
Then Tailer only rarely accesses the underlying system.
