1### General Info & Setup
2This script is used to measure the speed of document processing in CouchDB. It sends a request to the CouchDB scheduler endpoint and retrieves information about documents transferred. The script logs the speed (documents per second) into an output CSV file.

41. Run `https://gist.githubusercontent.com/ss186222/2f024da3d7f51c0c61b861bb424dfe33/raw/6dc09ed53872b70e93660f88e29684163131810a/cleanup.sh | bash` to clean the CouchDB cluster. Run this inside your edge-infra folder.
52. Run `kubectl port-forward -n data-sync-couchdb data-sync-couchdb-0 5984:5984` to establish port forwarding.
63. Finally, navigate to hack/datasync/ and run `python3 speedTest.py --maxjobs 10000 --churn 500 --interval 10000 --username USERNAME --password PASSWORD --serverURL http://localhost:PORT/` to start the replication speed test.

10- `maxjobs`: Maximum number of jobs parameter value.
11- `churn`: Churn parameter value.
12- `interval`: Interval parameter value.
13- `username`: Username for authentication.

18### Output
19
20The script appends the following information to the `output.csv` file:
21
22- Timestamp
23- Document ID
24- Number of documents written
25- Speed (documents per second)
26- MaxJobs parameter value
27- Churn parameter value
28- Interval parameter value

30### Data Analysis
31
32The `output.csv` can be analyzed in multiple ways. You can run [this script](https://gist.github.com/ss186222/588ea911d45e03e6326b8c000d7db40d) to perform analysis on the output data and identify the fastest churn/interval/maxJobs pair.View as plain text
