In a newly installed EPiServer CMS 5 R2 (64 bits) the loading of My Tasks -tab in Edit-mode is very slow. About 30 secs. What is this view doing exactly? The lists presented only contains about 40 items.Everything else is working fine. Could the slow performance be a result of too many windowsgroups imported by the windowsauthentication provider? About 1700 groups are listed at the moment and we are of course thinking about changing provider.
