Yes, qmail-queue is called per message and will load the file.
For us there was never a need to optimize the lookup since this feature
is a bit of a hack and evil and should only be used in exceptional
circumstances. The bigbrother patch was not built monitor large amount
of users. It is possible to intercept all mails from a single domain.
Why do you need to bigbrother 10k users?

~control/bigbrother
This file is only used if BIGBROTHER was defined in the Makefile.
For ISP that need to implement some surveillance method because of some
beloved authorities (like here in switzerland), you can enable a per
address queue extra feature. To automatically forward all mail to and from
bad...@badplace.ch to bigbrot...@admin.ch you need to add followong line to
~control/bigbrother: bad...@badplace.ch:bigbrot...@admin.ch.
bigbrot...@admin.ch can be a local, ldap or remote address.
To intercept all mails to and from a domain @badplace.ch can be used.
Default: none (off)
Example: bad...@badplace.ch:bigbrot...@admin.ch
Note: An extra recipient will be added in qmail-send. If the bigbrother
address causes a bounce the sender will see this bounce.
Btw. qmail-cdb should be able to create a cdb file out of bigbrother
without an issue.
