JAMES-3995 Optimize Email/get method #5066

Closed Arsnael closed 6 months ago

Arsnael commented 7 months ago

For Email/get, we seem to buffer body binary parts using Mime4J to be able to recalculate the size of the part.

This causes James to consume a very high amount of memory, which can cause performance issues if there is too many of those.

We should try to find a way to avoid buffering the binary parts in order to save memory, and boost performance for Email/get JMAP method.
