Assignee board take 10s + to load for each user

Our assignee board take forever to load. Planning board and Task board are working fine too. Only this one is 'freezing' the browser (IE7 or Chrome same thing).

I have about 20 assignee for that project so its not a lot. And a example of 6 issues on a assignee it take about 3 seconds by issue to show up.

Using lastest version.

Thanks
