Hi,
we are using Sabre DAV. Very stable and its performance depends on the performance of your webserver.
We are using Apache-MPM prefork. If your webserver can handle HTTP-requests for 10k users, it will handle CARDDAV/CALDAV-requests for that amount of users as well.
If you are familiar with php-programming, you may extend Sabre DAV. Standard Sabre DAV has its own user database. We extended the SabreDAV authentication mechanism such that user-credentials are pulled from the same database that Dovecot is using.

I hope it is ok to post this off-topic question here. I was wondering if there are here environments running that offer next to dovecot also calendar and contacts services. In the past I was testing a bit with the one from Apple, but I think it is being discontinued because of converting the python 2 code.
I am looking for some experience with a setup provisioning >10k users. Not that I have such requirement, but I want to know if the solution is stable, efficient and optionally can scale. I need something efficient, because I do not have to many resources and high iops available. I also do not want any other other 'crap' just the cal (and card) dav solution.
