We encountered strange behavior, recently when we sent campaign using multithread it starts to send with full speed but after few minutes it slows down and stays at around 300-400 emails per minute.
This happens suddenly as previously we sent few campaigns and all was good but now nomatter what we do it slows to max 400 per minute.

Have you checked the connection (ping time), and if the other side has changed anything (especially limits)?
Perhaps your server/smtp is overloaded?
Look into every available log and take the process apart to find the bottleneck.
Post any further details you find.
