1 - you can't (except perhaps with the recent queue mirroring feature
which hasn't yet been released). However you can at least guarantee
that the message has been persisted - either by publishing it within a
transaction (once the transaction is committed, you're sure its
effects are permanent), or by using "publisher confirms"
2 - yes, it does effect the performance IIRC. I had a server slowed
down to a crawl and then crash when it had several thousand (mostly
unused) queues.
