SubjectRe: Got iperf regression while intel_iommu is on, how to cut the cost of cache flushing
From
Jiang,
Could you help to take a look such performance issue about Intel
IOMMU, seems you go back this field of Intel. Is it possible to
eliminate the performance side effect of mapping and unmapping
operation ? some context information, please refer to the first mail

Thanks,
Ethan
