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
