This uses 10290.40 MB total, if we pad with zeroes (9.08GB plus 992.48MB). >>> without inline: >>> real 4m42.085s >>> Data: total=11.01GB, used=10.85GB >>> Metadata, DUP: total=1.00GB, used=518.59MB Under the same assumption, this uses 11628.99 MB total (10.85GB + 518.59MB). >> I suggest you take a closer look at your numbers. > > both use 12GiB in total and both need 280 seconds. > am i missing something? With inlining, you're using about 1.3 GB less disk space and require a few seconds less wall-clock time for the same thing. A 10% difference in storage space requirement does not seem like "no benefit" to me, and both sets of numbers favor the default (with inlining). -- Michael Kjörling • http://michael.kjorling.se • mich...@kjorling.se “People who think they know everything really annoy those of us who know we don’t.” (Bjarne Stroustrup) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
