But running these tests illustrate quite well that there is diminishing returns or serious tradeoffs required to reach for the biggest compression ratios. Either they do not perform as well as a lower ratio, they take inordinately long time to run or they require bespoke solutions (like custom dicts tailored very specifically to what you are trying to compress). Saving bandwidth is a laudable goal but can not lose sight of practical issues. :) -- Kind regards, /S -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
