Performance Testing

Mobibench

  1. Clone the source repository of Mobibench fork for Limbo:
git clone git@github.com:penberg/Mobibench.git

  1. Change LIBS in shell/Makefile to point to your Limbo source repository.

  2. Build Mobibench:

cd shell && make
  1. Run Mobibench:
./mobibench -p <benchmark-directory> -n 1000 -d 0 -j 4

Clickbench

We have a modified version of the Clickbench benchmark script that can be run with:

make clickbench

This will build Limbo in release mode, create a database, and run the benchmarks with a small subset of the Clickbench dataset. It will run the queries for both Limbo and SQLite, and print the results.

Comparing VFS's/IO Back-ends (io_uring | syscall)

make bench-vfs SQL="select * from users;" N=500

The naive script will build and run limbo in release mode and execute the given SQL (against a copy of the testing/testing.db file) N times with each vfs. This is not meant to be a definitive or thorough performance benchmark but serves to compare the two.
