# Enable compression for site minio1
./mc admin config set minio1 compression enable=on extensions=".txt" --insecure

Example: The following settings will increase the heal operation speed by allowing healing operation to run without delay up to `100` concurrent requests, and the maximum delay between each heal operation is set to `300ms`.

```sh
~ mc admin config set alias/ heal max_sleep=300ms max_io=100
```

Once set the healer settings are automatically applied without the need for server restarts.

## Environment only settings (not in config)

        RdmaStatistics stats = new RdmaStatistics();

streaming compression due to its stability and performance.

This algorithm is specifically optimized for machine generated content.
Write throughput is typically at least 500MB/s per CPU core,
and scales with the number of available CPU cores.
Decompression speed is typically at least 1GB/s.

This means that in cases where raw IO is below these numbers

    runner.close();
    runner.clean();
}
```

### Testing Best Practices

- Minimize `Thread.sleep()` - use only when absolutely necessary
- For timestamp tests: use minimal delays (50-100ms)
- Clean only test-specific indices (not `_all` unless needed)
- Use `runner.refresh()` after index operations
- Test with realistic multilingual content
