Design a distributed rate limiter that works across multiple servers without a central coordinator. Use a sliding window algorithm. Handle clock skew between nodes. Show the implementation.

In addition to the above requirements, implement a feature that allows for burst traffic handling. The system should be able to handle short bursts of requests exceeding the average request rate within a given time window. This means implementing a token bucket algorithm in conjunction with the sliding window algorithm.

Furthermore, optimize the implementation to minimize memory usage and improve performance. Instead of maintaining separate counters for each server, utilize a shared data structure to track request counts across all servers efficiently.
Here's an implementation of a distributed rate limiter using a sliding window algorithm with burst traffic handling:

```python
import threading
from collections import defaultdict

class DistributedRateLimiter:
    def __init__(self, max_requests_per_window=10):
        self.max_requests_per_window = max_requests_per_window
        self.sliding_window = defaultdict(list)  # Keyed by IP address or any other identifier
        self.token_bucket = {}  # Keyed by IP address or any other identifier
