Its total pause time is 24.9% to 62.1% shorter than that of the garbage collection in Harmony M2 on Intel dual-core platform. Its performance is improved 20% in average. The detail experimental result is in the attachment. (My development environment is 5.0M2). > In the attachment there are the souce code, compile configure file and test report. > The following are the two parameters In my garbage collection. > -XX:gc.corenum=core number default value is 2 i.e -XX:gc.corenum=2 > -XX:gc.blocksize=block size default value is 64 i.e -XX:gc.blocksize=64 > I am very glad to get some comments from everyone. > Thank you. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
