I've been assigned the task of finding out just how fast the network performance of our new boxes are and I need some software to help me do this. I'm looking for something that will let me blast out lots of packets of various sizes. Being able to send packets via different protocols would also be nice as we need to get a handle on TCP as well as UDP performance. Something that would also let me send ill-formed packets to see that we don't choke on such critters would also be nice. Obviously, I need source code. Our box is a mix of System V & BSD so I'm prepared to do some porting. I just didn't want to have to reprogram the wheel. Does anyone out there in net.land have or know of any benchmarking programs that will help me get these numbers? Can you send me email telling me about them? I thought you could. :-) -- Adam S.
