.NET Messaging Q performance wrt message size

Question

I got the following observation with the use of .NET messaging queue: Message size = 1K, message per second = 5000 Message size = 200K, message per second = 102 Message size = 500K, message per second = 43 Is there a way to improve the .NET messaging queue performance when increasing the message size ? I've been using binary formatter. Also I got the "System.Messaging.MessageQueueException: Insufficient resources to perform operation" problem.
