Plotting Legacy vs Blobs results ================================ This script produces a bar graph comparing different implementations of the mail pipeline (legacy, blobs, blobs with session cache, blobs with session cache and persistent http connections) for different amount/sizes of incoming data (1 x 10M, 10 x 1M, 100 x 100K, 1000 x 10K). Data acquisition ---------------- Data was gathered through different runs of the code in `soledad/tests/benchmarks/test_legacy_vs_blobs.py`. As these tests are skipped by default, you have to (1) remove the @pytest.mark.skip decorator and (2) remove the second call to pytest in `tox.ini` that would cause a second run of the tests for measuring memory. This script only plots time, for now. Once you done the above, chdir into `soledad/tests` and do something like this, for each test group: tox -e benchmark -- -m benchmark_test_legacy_vs_blobs_10_1000k --benchmark-autosave Each run of tox as above produces a JSON file in `soledad/tests/.benchmarks` with stats. Each file has to be copied in a subdirectory of the `data/` directory of the folder where this script lies. Code has to be adapted for each extra set of results added to the `data/` directory. Currently, we are comparing 4 implementation variations: - data/no-cache: contains legacy as baseline and blobs as the current master implementation of blobs. - data/cache: adds twisted session cache to blobs connections. - data/persistent: adds session cache and persistent HTTP connections. Plotting -------- Once you have all your data in subdirectories of the `data/` directory and the script is correctly tuned for your data, running `make` should be enough to create a virtualenvironment with dependencies and plotting data. By default, the script will generate a file called `./legacy-vs-blobs.png` in the current directory with the plot of the data.
