Loic Dachary 81dee1b67f osd: erasure code benchmark workunit ... Display benchmark results for the default erasure code plugins, in a tab separated CSV file. The first two column contain the amount of KB that were coded or decoded, for a given combination of parameters displayed in the following fields. seconds KB plugin k m work. iter. size eras. 1.2 10 example 2 1 encode 10 1024 0 0.5 10 example 2 1 decode 10 1024 1 It can be used as input for a human readable report.
