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.
Test:
-
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.
