One of the things about vimage is it changes *everything*, and adds an additional argument to all network stack related functions; although when Marko profiled it, he found that there was a slight performance increase (I think 2-3%) due to locality-of-reference L2 cache effects. Because it would have a substantial impact on the driver ABI, I think expecting to see vimage in 6.0 would be unrealistic, but it may be something to consider as an option for 7.0. Regards, BMS
