65444 DMA Driver for Win read Speed

Hi, I used 65444 DMA driver for Win7 64bit and executed the examples. Got the Write speed about 2.xGB/s, that's all  right. But when I red the DMA, the speed was about 100MB/s. I tried severy times and the speed was still about 100MB/s.

I saw https://www.xilinx.com/support/answers/68049.html the page, the read speed should be faster than write speed.

whether I use the driver in a wrong way or there were any details I should know?

Thank you!
