Subject: [dpdk-dev] What is the impact of RTE_FORCE_INTRINSIC on performance
Date: Tue, 20 Feb 2018 20:48:43 +0200	[thread overview]
Message-ID: <CAOBqJ55vR3zHdArbMU7a_BO=bHAwVr9RLVA-gZBY4WKgkWVQNQ@mail.gmail.com> (raw)

Hi,

I'm running DPDK on Intel x86 processor which supports SSE2,
in my current deployment I didn't enabled RTE_FORCE_INTRINSIC.
After reading on Intel's intrinsic pause I wonder if I should enable it or
not.
especially how it should impact on latency those noop command going through
the CPU.

Also, I wonder does it matter if I have contention on shard objects pool
and on spinlocks?

Thanks,
Roy
