Forum OpenACS Q&A: Response to Handling large numbers of users

i like the idea of scalable ui's. for dotlrn i built a scalable ui for user administration. when the number of users is small (less than 50 or so) it simply displays them in a list. between 50 and 500 i add a dimensional bar that allows you to browse by first letter of last name. if there are more than 500 a search box is presented.

of course this adds the overhead of counting all the users for each request to the page, but this can be easily cached.

i'd like to see this type of ui used more in openacs.
