Hi James, I have not tried it. My one thought is that gzip compression is CPU intensive and slow in terms of MB/sec processing speed. That seems like it would not be particularly useful on a server processing a LOT of logging. For more moderate use, it could be advantageous. Now if gzip were replaced with a higher performing algorithm like lz4 or snappy, it could find a use at the top end.
