Stats extracted from Index.Stats.get ().

new_merge_durations is not just a mirror of Index.Stats.merge_durations, it only contains the new entries since the last time it was recorded. This list is always empty when in the header.

Stats extracted from filesystem. Requires the path to the irmin store.

Melting pot of stats, recorded before and after every commits.

They are necessary in order to compute any throughput analytics.

Sourcetype store_after = V0.store_after = {
