1. Internet throughput with acknowledged protocols, such as TCP, are capped by the formula (Buffer Size)/(Ping Time). Assuming round trip acknowledgement latency cannot be controlled, bigger buffers must be used to increase throughput. Internet performance is derived from LAN throughput and is not measured.
2. Stack performance with a dsPIC33F is identical to a PIC24H device at the same processor clock. No DSP features are used by the TCP/IP stack.
3. ENC624J600 and PIC32MX7XX/6XX Internal 100BaseTX Ethernet measurements are done in 100Mbps, full duplex mode.
