Yes, I am happy to see it reduces the size of each payload. but sometimes smaller memory footprint doesn't change to runtime performance directly. From my measurement,  LogDecoration doesn't impact that much.

Check out this performance comparison. I found that copying 20 bytes is almost identical to copying 256 bytes.
