I'm writing a web app and using /wg/wrk to stress test it along with this tool but don't understand the output. Here's the CPU profile output after running wrk -t12 -c400 -d7s http://127.0.0.1:8080

Can you please paste the .svg output.

@davecheney Not sure if you wanted the text output or an svg image but here's the text output

Also this is the stress tester's output in case that's relevant

Looking at that profile it looks like most of the time is being spent in
writing to the network, this doesn't look unexpected because this is a web
server after all.

@davecheney Yeah It's a simple web server but I was just curious as to what the numbers mean. Thanks anyway.
