Here are limitation about IMAP migration, there doesn't exist limitation on number of mailbox during migration:

About the migration speed, there doesn't exist article introduce about it. I guess it decided by the network and distance between the data center that hosted your tenant.

By the way, Microsoft provide the Cross-tenant mailbox migration (preview).
