    Description

      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.
