I did a test shown as following diagram. (The DUT is running Linux with NAPI ethernet driver.) I add 1000 routes into DUT then use the Smartbits port1 to send packets (with destinations to all the 1000 networks) to the DUT then receive them back from the port 2. The packets are sending in a rate that is much lower than half of throughput of the DUT. The DUT will lose some packets if the DUT has empty route cache before the packets are sen...

The problem is with 1 test because i received full ba...

...ation because i would like more packets/sec !! this is the scenario of the performance test: i''m using an embedded system with: SPEED CPU: 399,999 MHz RAM: 128 MByte FLASH: 16 MByte EEPROM: 8Kbyte PROCESSOR MPC8272 a lan to lan 10/100 and in particular we are sending packets from a smartbits (packet generator) to the embedded system above in the interface eth0, 10.0.0.2 -> passing trough QOS with HTB (embedded system)-> sending back traffic through the interface eth1 which is attached to the smartbits on another interface to measure received packets. with packet length...

Dear best guys, I really love 5.3 in many ways but here're some unbelievable transfer rates, after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve my performance problem (*laugh*): (In short, see *** below) Tests were done with two Intel GigaBit Ethernet cards (82547EI, 32bit PCI Desktop adapter MT) connected directly without a switch/hub and "device
