Benoit Tellier created MIME4J-303:
-------------------------------------
Summary: Base64OutputStream is two time slower than its Java8
counterpart
Key: MIME4J-303
URL: https://issues.apache.org/jira/browse/MIME4J-303
Project: James Mime4j
Issue Type: Improvement
Components: core, dom
Affects Versions: 0.8.5
Reporter: Benoit Tellier
Fix For: 0.8.6
While looking and running mime4J benchmarks, I tried some alternative
implementations for Base64 encoding / decoding.
Base64InputStream proved to be 20% faster than its Java8 counterpart.
However, throughtput went from 280 MB/s to 520 MB/s by switching to Java8
Base64.getMimeEncoder().wrap(...)
Tests pass and this speeds up message writing operations... Apache James can
for instance beneficiate of it when composing JMAP messages with large
attachments.
