[jira] Created: (HARMONY-5513) Class data sharing support for
DRLVM
Class data sharing support for DRLVM
-------------------------------------
Key: HARMONY-5513
URL: https://issues.apache.org/jira/browse/HARMONY-5513
Project: Harmony
Issue Type: New Feature
Components: Contributions
Reporter: Roman S. Bushmanov
This is a contribution of CDS support code for DRLVM.
That was developed in Sept 2006. I'm am attaching it as an archive containing the files which were added or modified while implementing the feature. I didn't do any merge with current drlvm sources. I hope the code will be useful to enable CDS feature in the current drlvm.
The attache code allowed storing of an image of classes into a shared archive and loading the archive at further vm startups. The list of classes to be stored was read from an external file.
A the moment I last tried the code, It was able to run EHWA on windows and "Hello world" on linux.
Performance gain at startup was ~10% on "Hello world" application and 1-2% on Eclipse startup.

Vladimir Beliaev commented on HARMONY-5513:
-------------------------------------------
I see no attachment in this JIRA appeared last two weeks. So it looks like Roman has changed his mind about attaching patch and JIRA can be closed.
Could someone close it as WON'T fix, please?
