Hi Robert,

The reason we didn't go with xz compression in the past (we looked into it) is because you cannot open a xz file natively in the browser. It's nice especially for folks who spend a lot of time looking at logs to be able to navigate to a log file on the server and click and have it immediately open. If we compressed with xz this would become an inconvenient 3 step process where you have to first download, then decompress, then open.

With that consideration I think staying on gz compression would be best until xz files can be opened directly from browser like we can with gz.

Regards,

Thanh
