My DBA engineer have seen around 20% improvement on sqlserver workload vs 2MB hugepages,
but I don't have a reproductible benchmark.  (It's was stats on real workload on a 1week stats summary)


Note that hugepage is needed for dpdk, and if you want some dpdk benchmark results:

1cpu core
---------
ovs      : framesize:64Bytes    result:  1,103,295 pps
ovs+dpdk : framesize:64Bytes    result: 16,766,108  pps

so, x16

Do we have some benchmarks now? I would really like to have 
a (simple) test setup where we can test the benefits of this 
option. Or is this too difficult to benchmark?
