Subject Re: inmemory mailbox wrong configuration
Date Wed, 06 Jun 2012 12:24:20 GMT
Ok, I'm sorry to spam about this question, but I would really like a response.
I am making assumptions, which may be incorrect.
Because of maven it is difficult for me to get a full source tree to read.


1.  Does james block on a single connection?
(I assume no, because this would be just be crazy)

2.  Does james block on a transaction within a connection, meaning server X talks to you on
a single connection, transmits M1, M2, M3.
Does james receive M1, queue a transaction in a different thread, and continue on to M2, -OR-
does it receive M1, block on transaction processor, and then continue onto M2?

(I hope doesn't block, if so I should implement a thread pool for the mailbox-write.)


Thanks,

-tim
