python3 bench.py

clone: git clone https://gitlab.com/jestdotty-group/draft/jisspam.git jest_rust

edit make: vi makefile and add build:

build_jest:
	@echo "compiling jest_rust project"
	cd jest_rust && cargo build --release && cp target/release/jisspam ..

append to all script:

all: build run valgrind build_risspam run_risspam build_cpp build_borded_cpp build_py build_jest

add to bench: vi bench.py

time_start = time.time()
subprocess.check_output('./jisspam books/*.txt', shell=True)
print("Time Jest Rust:", time.time() - time_start)

run: python3 bench.py output looks something like this:
