Hello all;
Please help me to understand the am18xx's performance issues with CDC/RNDIS section:
on this link:
it says the performance of
USB Mass storage - Write: 24 mBytes/s at 96% cpuload
Sata writes: 26 mBytes/s at 99% cpu load
Ethernet : 78 mbits/s at 100% cpu load.
but usb-CDC: 49mbits/s at ??? cpu load.
CDC is on usb high speed(480 mhz) ; so why only 49 mbits?
what is the cpu load ? (100%?)
so is the conclusion that CDC/RNDIS on the HS usb are much slower than Ethernet's 100 mhz ?
Please help me to clarify. thank you.
