This is due to check sum handling issue in the vmxnet3 driver. Fix is on the kernel tree. https://git.kernel.org/cgit/linux/kernel/git/stable/linux- stable.git/commit/drivers/net/vmxnet3? id=f0d437809d23999cb25207cfbe80c61e5703fdc1 I have tested the fix and confirmed to resolve the performance issue with LRO. Thanks Ram
