Possible bug in dovecot doc

Dear maintainer,

there is potentially conflicting information in dovecot doc about the count quota backend.

According to https://doc.dovecot.org/configuration_manual/quota/quota_count/ the count quota backend is the recommended way of calculating quota on recent Dovecot installations.

But according to https://github.com/dovecot/core/blob/main/doc/example-config/conf.d/90-quota... it is extremely SLOW with Maildir. It'll eat your CPU and disk I/O.

I don't think the information on github is true, but I could be wrong.

Could you fix/clarify this? Thank you in advance.

Best regards Petr Sorm
