Performance test of Xeon D with Optimized LINPACK

Hi,

I evaluated my embedded board, which has Xeon D 1.7GHz(8-cores, 12MB cache and 32GB DDR).

I expected about 400 GFLOPS but the result was about 145 GFLOPS. I would like to know the result is reasonable or not, and then how to get maximum performance.

Thank you.
