[Lxc-users] LXC vs ESX

[Geordy]

Hi,

Which 10 gb adapter did you use in the esx box? I have test data on a broadcom 10 gb adapter that shows very poor results in thruput. The problem is that the chip on the broadcom only pump 25% of the 10 gb when talking to non broadcom adapters. We have several level 3 calls open regarding this. One of my clietns for example has 4 x 10 gb on an lacp but will only manage to fill 7% on a single threaded tcp ip transfer, when he uses multiple tcp threads to transfer gpfs data he suddenly reaches 90%.

i do not know this tool but try the same using iperf and set it up using multiple streams... You will get higher values.

My 2cents
