I've been using this for a couple of days and it's working fine. The default configuration file uses max_pool_percent=15 compressor=zstd zpool=zsmalloc accept_threshold_percent=90 shrinker_enabled=Y Reported compression ratio is 4.22. Documentation says zbud compression ratio is fixed at 2:1. So zstd/zsmalloc is an obvious improvement. We're already using zstd elsewhere in Fedora. Should we update https://fedoraproject.org/wiki/Zswap to reflect using this package? I like the systemd service unit approach, which then pokes sysfs appropriately. -- Chris Murphy -- _______________________________________________ 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
