I have been using
ohaa lot for my projects and wanted to share that the Tokio async runtime causes a lot of CPU usage under certain conditions.You might want to consider documenting this or adding a command line arg for it.
As an example:
warpserver: https://github.com/the-benchmarker/web-frameworks/tree/master/rust/warpohaandwarpreach ~130k RPS out of boxohauses ~300% CPU to achieve this on a 12 core M2 MaxTOKIO_WORKER_THREADS=2 oha -c 100 -z 10s http://127.0.0.1:3000/user/12345667Incidentally, I made a couple of YouTube videos about this and used
ohato test both my framework and other frameworks. You can seeoha's histogram dancing around for about 10-15 minutes across the two videos. I thought you might like to see that!Beta Was this translation helpful? Give feedback.
