Hi Kevin, My dom0 memory is the default 512MB, domU is 1GB (7GB in the system, 2-way w/ default vcpu to phys cpu mappings). My throughput test is simply pulling a ~300MB file from a local server using wget. Something like: wget -O /dev/null http://local.server/big_file Wget provides a progress report and average throughput at the end of the transfer. Let me know if you get different results, I tried several times and seemed to get consistently degraded performance with the event callback patch.
