Frequency of information update in "Users" section (updated)


Maybe this section is still in development process but how often the data is updated here (loaded from the database)? Because right now information in “Users” section differs from what I can see in personal profiles of members.
UPDATE: New users also display in Users section with delay, right now forum has been launched, new users begin to register and I see them in topics, they are also taken into account in user counter from “About” section but I don’t see them in “Users section” and they aren’t counted in total number of users here. I guess it can cause a big load if ask database for actual info about users everytime when “Users” section is opened but I suppose it would be good to refresh data here at least every hour. FYI @ibby
