There is one now: https://issues.jboss.org/browse/ISPN-1801 > 3. https://issues.jboss.org/browse/ISPN-1788 - config parser out of sync with > XSD! > 4. https://issues.jboss.org/browse/ISPN-1798 - forceReturnValues parameter in > the RemoteCacheManager.getCache() method is ignored! I'm sure there will some others as community starts reporting! but that's good as we can provide a quick release for the main issues. > In addition, we may as well have these "nice to have's" in as well: > > https://issues.jboss.org/browse/ISPN-1787 > https://issues.jboss.org/browse/ISPN-1793 > https://issues.jboss.org/browse/ISPN-1795 these ^^ are already in master so we can include them straight away. > https://issues.jboss.org/browse/ISPN-1789 this looks like a low prio, as doesn't have an impact on the functionality > https://issues.jboss.org/browse/ISPN-1784 pull request sent, so IMO makes sense. > > What do you think?

As everybody is in the performance min set, I think the following issues, in this order, would be a quick win: https://issues.jboss.org/browse/ISPN-825 https://issues.jboss.org/browse/ISPN-317 https://issues.jboss.org/browse/ISPN-1748 I don't think implementing them would take more than a week's time, and their impact on performance is massive. During this week we can also gather and fix the most critical issues raised from 5.1.Final. Cheers, Mircea
