             Summary: Configure MimeMessageInputStreamSource THRESHOLD
                 Key: JAMES-3487
                 URL: https://issues.apache.org/jira/browse/JAMES-3487
             Project: James Server
          Issue Type: Improvement
          Components: James Core
            Reporter: Benoit Tellier


This represents the point at which we should switch from a memory storage into a file \
storage.

Defaults is 100 Kb.

Obviously this parameter is important:
 - Higher values will operate mostly in-memory thus will have low latencies but will \
                trash the heap and might trigger a GC hell.
 - Lower values will defensively operate on files. Higher latencies but predictable \
throughtput. Modern SSDs and FS cache should enable to keep up with high rates.

Optimally we should have some bench showing the impact of this parameter.

Related to JAMES-3477.
