I was wondering if some of you have been experiencing performance problems using the journal module or your administrators reported you any slow process related with the journal module. Pau Ferrer contributed a patch improving the performance of the module when viewing the number of journal entries and I've contributed a few more improving the cron process that sends emails. I would prefer to include those changes only in master (or also 2.8 as it has just been released) but I am not feeling like backporting it to 2.7 and 2.6 as the changes have not been properly tested in real environments, only in testing environments but I would reconsider it if some of you are experiencing important performance issues. Please, comment if that's the case. Thanks in advance.
