vector_add example - measuring the performance

Hello,

I have executed the vector_add example on the DE10-Standard board and got the following output. It took 6.9ms kernel time to perform the floating point add operation on 1M elements. So, the performance is around 145M FLOPS. I expected the performance to be much higher in the order of 100 Giga FLOPS. Is there a way to achieve a better performance?
