Performance Testing

Mobibench

1. Clone the source repository of Mobibench fork for Limbo:

git clone git@github.com:penberg/Mobibench.git

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

3. Build Mobibench:

cd shell && make

4. 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.

TPC-H

1. Clone the Taratool TPC-H benchmarking tool:

git clone git@github.com:tarantool/tpch.git

2. Patch the benchmark runner script:

diff --git a/bench_queries.sh b/bench_queries.sh
index 6b894f9..c808e9a 100755
