I have a striped lock manager in 3.x (currently in dev, alpha soon out) which can potentially be backported to 2.2.X. This will limit the locks created and the corresponding overhead. If you think you can wait for 3.x (should be released in a couple of months, with alphas and betas in the coming weeks) then great. Otherwise, raise a JIRA to backport this striped lock manager to 2.2.X. and it could be in 2.2.1 as an option.
