             Summary: Improve performance of read on Paging
                 Key: ARTEMIS-1214
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1214
             Project: ActiveMQ Artemis
          Issue Type: Improvement
            Reporter: Francesco Nigro
            Assignee: Francesco Nigro


Speedup reads trying to exploit the Linux Page Cache (eg LMDB) while reading a Page using
READ-ONLY mapped regions of the written Page and avoiding to allocate big direct buffer to
do the same.
This could work only with SequentialFile implementations that rely on the Page Cache (only
MAPPED and NIO right now).
