Feature

• please use two terminals

• terminal 1

  cd src
  make clean
  make build
  sudo python3 bpf_run.py
  # hint: when io_call finish, use CTRL+C to get the results

• terminal 2

  ./io_call

Result & Analysis

In my experiments, I used eBPF as a tool to measure function call time. io uring at the time of writing the file, including the commit time of sqe and the time of harvesting cqe. Therefore, the time to add the two in the experiment is the time required for io uring writing. Compared with the general io method, the read and write speed of io uring is nearly ten times faster.

liburing average call time: 753.0306 ns
blockio average call time: 4481.6288 ns
