Q: In the case of a large number of iPortal users, for example: 20, 000 users, start iPortal service will be slower, the loading of user management page will be slow too, how to solve?
A: When iPortal service starts, it caches all the users' information into
memory by default, all the following operations on querying users' information
will be based on memory. When the number of users is large, it is recommended to
disable the caching operation to improve the performance. Open the
iserver-system.xml file under [SuperMap iPortal_HOME]\webapps\iportal\WEB-INF,
true means that caching all the users' information into memory. When the amount of user data is large, it is recommended to set it to false to disable the caching operation.
