Hello, I'm planning to activate quota control in dovecot, with maildir quota backend. I have about 70k users in my system directed to 4 backend servers (with a director to ensure that a user is always directed to the same server). I have tried to activate it in one of my nodes. The problem is that load of it has increase a lot, as much as the system was unusable (maildir is in nfs storage, with indexes in local disks). What do you think is the best to activate it? I have think that I could use doveadm commands to calculate an initial quota (on low load periods) and then activate quota, hoping that although quota is not correct, it would be used. Should this work?

I think that nfs storage is a very common scenario.
