This project is no longer maintained. In addition to the caveats listed below, it has not been updated for the latest versions of packages and has some known problems such as #6.
This benchmark should not be used as-is as a performance comparision between
async-std and tokio. It was designed to highlight certain pathological
cases and does not reflect a realistic or recommended usage pattern.
There are several issues with using this as a direct comparative benchmark:
- The number of tasks and buffer size are unrealistic, and adjusting them can affect results dramatically.
- It uses default configurations of both libraries. These default configurations might not actually be suitable for this workload, and even under default operating system configurations this benchmark will not run.
The benchmark is most useful for tracking changes in executors, e.g. "did change X really improve Y, as measured by this benchmark", and as a stress test.
You'll need a file.dat. For example, 256KiB of random data:
dd if=/dev/urandom of=file.dat count=256 bs=1024
You will probably need to raise your open files limit to run this:
ulimit -n unlimited
