Subject Re: Synchronized methods in ItemManager
Date Mon, 17 Sep 2007 19:12:38 GMT
Reading this post and going through some of the work I have done re. 
syncronization in the persistence manager I wonder if the real issue is 
not threads sharing a session, which it is clear they shouldn't, but 
that each session is tied to a persistence manager and an item manager 
which are both heavily synchronized. I understand the need to keep 
caches in sync etc, but it seems that we could be more performant (and I 
know I still owe the group numbers for performance :-) if we could use 
another pattern such as reader/writer locks, etc. to ensure consistency 
but allow for multiple simultaneous reads and writes.
