I send data from evaluation board MCB2300 (with LPC 2378 microprocessor) to a user's PC via Ethernet using TCP/IP protocol. A program named Ethereal shows that MCB2300 transfers 1024 bytes segment during 7-8 ms after ACK is received from PC. Why the transfer is so low? (Program sample is EasyWeb).
When we were conducting our tests, we transmitted 16Kb blocks.
Each TCP packet was 1Kb, so there were 16 transmissions.
It initially took 7.6ms to send the complete 16Kb block.
By increasing the TCP tick frequency, we could achieve the same transfer in 4.2ms.
Very acceptable.
