+## About
+Analyzes the long_calls.txt file produced by obs-studio-node and helps identify which methods take the longest.
+
+## Detailed breakdown
+* Mass download hundreds of latest user caches from AWS bucket streamlabs-obs-user-cache
+* Extracts long_calls.txt and load its data into a database, with minimal filtering; for example, avoiding counting files from the same user multiple times.
+* Run some basic statistics to identify which IPC calls cause the most trouble and are worth checking if we want to improve performance.
+
+## Requirements
+Node 22, Access to AWS S3 bucket
+
+## How to run
+```
+yarn install
+yarn build
+node dist/long-calls-analyzer.js --age 1w
+```
