Description
The org.apache.jackrabbit.oak.plugins.segment.file.TarFile constructor reads through the whole tar file, building up an in-memory map from segment uuid to the position in the file. This is done each time the repository is started, and it takes quite a long time.
This index should be persisted somehow. See the discussion in http://oak.markmail.org/thread/dlnb2mfbbui67b75
