+# AWS EC2 Benchmark Guide
+
+This guide explains how to run Memori benchmarks on an EC2 instance in the same VPC as your AWS database (RDS Postgres or MySQL).
+
+## Setup on EC2
+
+1. **SSH into EC2**:
+   ```bash
+   ssh ec2-user@your-ec2-ip
+   ```
+
+2. **Run Setup**:
+   Copy `tests/benchmarks/setup_ec2_benchmarks.sh` to your EC2 or clone the repo and run it:
+   ```bash
+   chmod +x tests/benchmarks/setup_ec2_benchmarks.sh
+   ./tests/benchmarks/setup_ec2_benchmarks.sh
+   ```
+
+## Running Benchmarks
+
+The `run_benchmarks_ec2.sh` script is flexible and handles automatic CSV generation.
+
+### Environment Variables
+
+- `DB_TYPE`: `postgres` (default) or `mysql`
+- `TEST_TYPE`: `all` (default), `end_to_end`, `db_retrieval`, `semantic_search`, `embedding`
+- `BENCHMARK_POSTGRES_URL`: Connection string for Postgres
+- `BENCHMARK_MYSQL_URL`: Connection string for MySQL
+
+### Examples
+
+#### Run all Postgres benchmarks
+```bash
+export BENCHMARK_POSTGRES_URL="CHANGEME"
+DB_TYPE=postgres TEST_TYPE=all ./tests/benchmarks/run_benchmarks_ec2.sh
+```
+
+#### Run only End-to-End MySQL benchmarks
+```bash
+export BENCHMARK_MYSQL_URL="CHANGEME"
+DB_TYPE=mysql TEST_TYPE=end_to_end ./tests/benchmarks/run_benchmarks_ec2.sh
+```
+
+## Results
+
+All results are automatically saved to the `./results` directory with a timestamp to prevent overwriting:
+- JSON output: `results_{db}_{type}_{timestamp}.json`
+- **CSV Report**: `report_{db}_{type}_{timestamp}.csv`
+
+To download the CSV reports to your local machine:
+```bash
+scp ec2-user@your-ec2-ip:~/Memori/results/report_*.csv ./local_results/
+```
+
+## Database Connection Requirements
+
+Ensure the EC2 Security Group allows outbound traffic to the database on ports 5432 (Postgres) or 3306 (MySQL).
+The database must be in the same VPC or accessible via VPC Peering/Transit Gateway.
