I am currently scoping a project that needs to be reworked so Umbraco V8 is part of it. This projects already has 18 000 members and 5 000 more are for sure on their way.

1. Does anybody here had experience with Umbraco with so many members? And if so what should I expect and beware of?
2. Another thing is: I will need to generate public profile pages for each member. (creating-a-public-profile-page-for-members-in-umbraco <- Any idea 💡 of how efficient is this approach ? )

My primary concerns are:

• Is Umbraco capable of handling this amount of members without taking a hit on the performance when loading information from the members
  property?
• Should I add my own tables to help the performance?
• Having 25,000+ member nodes how much will it slow the manegment of the members via the Umbraco interface. However what if I just use my own manegment tool for this level of members?
