Hi,
This is re:
http://community.jboss.org/wiki/PossibleLockingImprovements
I've created JIRAs for the locking optimisations as follows:
#1:
https://issues.jboss.org/browse/ISPN-1131
#2: this seems to be just a particular case of #4
#3:
https://issues.jboss.org/browse/ISPN-1132
#4:
https://issues.jboss.org/browse/ISPN-1137
#5: I think this is pretty much the same thing as #4, waiting for Sanne to confirm that.
Each JIRA also contains the design I have in mind for implementing them.
I do think this will improve the transactional throughput *significantly*, so any feedback
much appreciated.
Cheers,
Mircea
