Freeware Review 1: Qcheck performance test

I was assigned to do the performance test for Motorola Canopy Access Points and Subscriber module. With the absence of a reliable tool, i have to search for some software in which i can do comparison. Basically, i need the response times, throughput and streaming test. Then i stumble upon these freeware from IXIA, which is very useful for a basic network test.You can select what protocol to use (TCP,UDP,IPX,SPX) and set the data size for response and throughput test. You can also do streaming test with UDP or IPX protocol at different data rates. You may want to check it it out HERE.
