I want to get a an idea of the rng throughput on machines different than mine so I can have an idea on a seinsible default to rate limit virtio-rng’s access to a guest will be.
The current limit of 1 kb/s is extremely low bordering on useless.
Note that you don’t have to be a Linux baremetal user to try this out.
Run: dd if=/dev/random bs=1k count=1 for 5 times then average the results
Please do not run any crypto intensive operations on your machine during this test as it will skew results because some of the rng input will be used up.
