    speed of USB3.0 by streamer

    sun.dekui

       Hi!

         

      I use streamer to read data from USB bord(3014). if I select 256 packets per xfer the speed can arrive at 320MBps. however after I detect the data I found that I lost some data. but if I select 8 packets or smaller the speed can arrive at 260MBps. but I can receive all the data. 

         

      So I want to ask that why I lost data with the larger number of packets per xfer.

         

      many thanks!
