 In practice ~50 users / Hue peak time is the rule of thumb. This is accounting for the worse case scenarios and it will go much higher with the upcoming Task Server [HUE-8738](https://issues.cloudera.org/browse/HUE-8738) and Gunicorn [HUE-8739](https://issues.cloudera.org/browse/HUE-8739) integrations. Most of the scale issues are actually related to resource intensive operations like large download of query results or when an RPC call from Hue to a service is slow (e.g. submitting a query hangs when Hive is slow), not by the number of users.
 
-Hue comes with caching of SQL metadata throughout all the application, meaning the list of tables or a database or the column description of a table are only fetched once and re-used in the autocomplete, table browser, left and right panels etc.. The profiling of calls adds in the logs with a total time taken by each request automatically logged.
