Hi chaps, I'm investigating a latency issue when sending data over a long fat connection, we are using QuickFixJ with it's default distribution of mina-core-1.1.0.
I notice that DIRMINA-561 addresses scaling receive windows and that this is released in 1.1.7. I'll try this release on Monday. I found DIRMINA -561 after reading this; http://www.psc.edu/networking/projects/tcptune/#Linux "NB: Manually adjusting socket buffer sizes with setsockopt() disables autotuning. Application that are optimized for other operating systems may implicitly defeat Linux autotuning." I was searching to see if Mina sets buffer sizes having read that doing so may defeat autotuning in Linux. I expect that this is a question that the Mina team may be aware of and I would be very grateful for any insight they may offer.
