[jira] Created: (HARMONY-5913) [classlib][pack200] Another
opportunity for buffering
[classlib][pack200] Another opportunity for buffering
-----------------------------------------------------
Key: HARMONY-5913
URL: https://issues.apache.org/jira/browse/HARMONY-5913
Project: Harmony
Issue Type: Improvement
Components: Classlib
Affects Versions: 5.0M6
Environment: Pack200 HEAD
Reporter: Andrew Cornwall
Attachments: main.patch
I found one more opportunity for buffering to improve the speed of the pack200 Archive API by about 8% when unpacking from one file to another.
This won't affect the performance of the Pack200.Unpacker API, but will serve as a useful example of why it's important to pass a buffered JarOutputStream in rather than a simple JarOutputStream on a FileOutputStream.
