Run cargo build --release to build the executables which are placed in target/release.
To host a server run:
crusader serve
It uses TCP and UDP port 30481.
To do a test run:
crusader test <server-host>
This produces an graph output file named plot.png.
There is also a binary with a graphical interface allowing you to use a client, a server and interact with results.

I really wish crusader had a mode to show what staggered start looked like. Staring up a zillion flows at exactly the same time is not how things really work on the internet.

Maybe the run time of the test could be made configurable? Often tests of longer durations like 0.5-10 minutes (so considerably longer than the typical 10-20 seconds for online speedtests) can be quite revealing and show e.g. things that cyclically affect throughput or latency (like an WiFi AP's channel scans say every 10 seconds).

The README now has a more expansive instructions for running the server and client. I'm not sure how to explain the green/blue colors of the latency plot.
I got the following error message when I ran the client without a server running at the other end.
A simple "No server seems to be running at <ip-address>" would suffice

First of all, a big thanks for this great software, which works really nice!
In the graphs, the latency for Up and Down is shown. I'm wondering how this is done considering that client and server are usually different machines with unsynchronized clocks?
