Realtime Marketing segments incredibly slow when loading members
Hello!
Had this very same issue with my recent client. Admittedly they have a very large number of contact (8 million) and we were segmenting on two custom tables, but even though the conditions in the segments were very simple (do not allow bulk email =allow plus a couple of conditions from a custom table), publishing is taking half an hour or longer.
Microsoft initially told me that up to 20 minutes to publish is 'acceptable' but they are now looking into solutions because the client is not at all happy.
Suggest logging a support ticket to see if there is anything that can be done to improve the speed of your segments.
