Hi Jorge, We're using the VirtIO driver, the MTU is 9000 and the physical NICs are 25G. The ports are grouped in bonds. ( 2 x 25G interfaces in a bond ) After additional tests we have seen the following: * between vm's on same host - speed is as expected * between vm's on different hosts in same cluster - speed is as expected * between vm's on different hosts and in different cluster - speed is much lower than expected. I was curious why the speed drops when we go across clusters, and was wondering if there are some limitations cluster wide or some tuning cluster wide that could be tweaked. /John /John
