Good morning: Let's say I've got two Dell 1800 servers and each one of these servers has dual gigabit Ethernet connections. The first connection on each server is connected to the corporate network at 100MB. The second connection is a cross-over between the two machines running at 1GB. One machine is running Fedora Core 3 and the other is running Redhat Enterprise Linux 3. I need to stress test and performance test this configuration by continuously moving large files back and forth under various processor loads for a given length of time and be able to show the results when completed. What are the best practices for the situation? Is there open source software out there to accomplish this or do I need to write something? I can think of a couple of shell script configurations to do this but I'd rather not reinvent the wheel if I don't have to. Thanks, -brian Brian D.
