How fast can the FX3 transfer data in superspeed mode?
We've observed the speed about 210MB/s in streamer application with P67 chipset and NEC controller.
this speed is too slow compare to superspeed 5Gbps and expected performance of FX3 even.
I wonder what is a bottleneck at this low speed among whole system components(south bridge, PCIe, NEC controller, FX3's memory architecture, DMA speed, host driver, f/w driver,...)
and is there any possibility of speed-up in official release version of driver and firmware?
In my application, the speed is very important factor, so I'd like to hear ways of speedup technique and the limit of FX3 if exists.
