Add benchmark script to compare two different builds of s5cmd #471

boraberke · 2022-07-22T11:26:24Z

This python script allow us to compare two different build (from either version tag, PR number or commit tag) performance under various scenarios. These scenarios include:

Upload, Download, Remove many small sized file
Upload, Download, Remove large file
Upload, Download, Remove very large file

To change the scenarios, you should edit it inside the bench.py for now. In the future, this could be read from a file. From each scenario, user should not forget to change the file size and file count keeping in mind the restrictions of their system.

To run use the following syntax:

usage: bench.py [-h] [-s OLD NEW] [-w WARMUP] [-r RUNS] [-o OUTPUT_FILE_NAME] -b BUCKET [-l LOCAL_PATH] [-p PREFIX] [-hf HYPERFINE_EXTRA_FLAGS] [-sf S5CMD_EXTRA_FLAGS]

Compare performance of two different builds of s5cmd.

optional arguments:
  -h, --help            show this help message and exit
  -s OLD NEW, --s5cmd OLD NEW
                        Reference to old and new s5cmd.It can be a decimal indicating PR number,any of the version tags like v2.0.0 or any commit tag. Additionally it can be 'latest_release' or
                        'master'. (default: ('latest_release', 'master'))
  -w WARMUP, --warmup WARMUP
                        Number of program executions before the actual benchmark: (default: 2)
  -r RUNS, --runs RUNS  Number of runs to perform for each command (default: 10)
  -o OUTPUT_FILE_NAME, --output_file_name OUTPUT_FILE_NAME
                        Name of the output file (default: summary.md)
  -b BUCKET, --bucket BUCKET
                        Name of the bucket in remote (default: None)
  -l LOCAL_PATH, --local-path LOCAL_PATH
                        specify a local path for temporary files to be loaded. (default: None)
  -p PREFIX, --prefix PREFIX
                        Key prefix to be used while uploading to a specified bucket (default: s5cmd-benchmarks-)
  -hf HYPERFINE_EXTRA_FLAGS, --hyperfine-extra-flags HYPERFINE_EXTRA_FLAGS
                        hyperfine global extra flags. Write in between quotation marks and start with a space to avoid bugs. (default: None)
  -sf S5CMD_EXTRA_FLAGS, --s5cmd-extra-flags S5CMD_EXTRA_FLAGS
                        s5cmd global extra flags. Write in between quotation marks and start with a space to avoid bugs. (default: None)

Examples

./bench.py --bucket tempbucket --s5cmd v2.0.0 456 --warmup 2 --runs 10

Above command will compare v2.0.0 to PR:456 with 2 warmup runs and 10 benchmark runs.

./bench.py --bucket tempbucket --s5cmd v2.0.0 456 --warmup 2 --runs 10 -sf " --log error" -hf " --show-output"

When using -hf and -sf flags, use quotes like above and start with an empty space. If not started with an empty space, it might give an error. This is a known issue with argparse and this discussion can be useful to understand the problem deeper.

Assumes that user has two copies of s5cmd one is default commandline app, second one is in the current directory. A bucket name MUST be provided with -b flag. User can optionally: - add a key prefix with -k flag. - specify hyperfine warmup counts with -w flag - specify hyperfine runs counts with -r flag. Example calls `./benchmark.sh -b mcanktmpbuck` `./benchmark.sh -w 1 -r 4 -b mcanktmpbuck -k example_key_prefix `

… the tests. user can specify either version(tag), commit hash, or the PR number of the s5cmd that are to be used in the tests. Two versions of the s5cmd will be used namely old and new. They can be specified by -o and -n flags, respectively. Though version specified by o does not have to be older than that of specified by -n flag. Default values of versions are v1.4.0 for old (-o), and v2.0.0 for new (-n). Example execution that compares performance of #456 with the v1.4.0: ` ./benchmark.sh -b mys5cmbuck -n 456 -o v1.4.0 -k 1829` Also note that user must provide a proper bucket which she has write/read/delete access.

Just updated from shell script to python script. Users now can use --help command to see the usage of this script 👍

also delete unnecessary file.

benchmark/bench.py

Before this commit, for each individual command, a scenario was required. These scenarios were dependent to each other. However, with this commit, any scenario will run `upload`, `download`, `remove` commands for a specified file size and file count.

Add a wait of 10 seconds after preparation to overcome errors due to eventual consistency of s3
