I have DE3 board with ETHERNET-HSMC CARD and I successes to porting udpofflaod example from alterawiki.
I face problem with throughput efficiency which is unacceptable for me, and I don't know if the problem from netwrok card on PC or on DE3 or there is missing configuration. The problem is: The number of packet/second is not change when payload size in ethernet frame change. for example: if I use maximum payload size 1500 byte, then: 81274.382 packet/second, throughput efficiency 95% (OK) if I use minimum payload size 46 byte, then: 81274.382 packet/second, throughput efficiency 4% (NOT OK) packet/second is not change and I see that on Wireshark software. The problem in throughput efficiency which is less than expected calculation, because the packet rate is the same. expected caluclation: if I use minimum payload size 46 byte, then: 1488095.238 packet/second, throughput efficiency 20% (OK)Link Copied
