To clarify, the issue that Pieter and myself are working on is how to increase the network throughput on his system. When you do the math, you can see that 128 times 64K buffers does fill pretty quick. And you need the virtual machine to get dispatched to consume that data. With sufficient virtual machines in queue, the time between two dispatches is enough to fill the buffers when you have multiple GbE adapters pumping data. I think his idea to use multiple NICs (so multiple sets of queues) is pretty smart. Too bad if IBM already knows it will now work. ;-) Rob -- Rob van der Heij Velocity Software http://www.velocitysoftware.com/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
