### Creating the `Settings` only once with `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then reuse the same settings object, instead of reading it for each request.

But every time we do:

```Python
Settings()
```

        });
        this.failoverStates = new ConcurrentHashMap<>();
    }

    /**
     * Handle channel failure
     *
     * @param failedChannel failed channel
     * @param error error that caused failure
     */
    public void handleFailure(ChannelInfo failedChannel, Exception error) {
        log.warn("Channel {} failed: {}", failedChannel.getChannelId(), error.getMessage());

        // Mark channel as failed

        // Test statistics reset functionality
        stats.reset();
        assertEquals(0, stats.getRdmaReads(), "Reads should be reset to 0");
        assertEquals(0, stats.getRdmaWrites(), "Writes should be reset to 0");
        assertEquals(0, stats.getBytesTransferred(), "Bytes should be reset to 0");
        assertEquals(0, stats.getOperationErrors(), "Errors should be reset to 0");

The unified KMS-based approach has several advantages:

- Key management is now centralized. There is one way to change or rotate encryption keys.
   There used to be two different mechanisms - one for regular S3 objects and one for IAM data.
- Reduced server startup time. For IAM encryption with the root credentials, MinIO had
   to use a memory-hard function (Argon2) that (on purpose) consumes a lot of memory and CPU.
