Subject: Percentage/ETA progress indicator faulty with examples/tiobench-example.fio
Date: Mon, 29 Jun 2015 17:21:15 -0600 [thread overview]
Message-ID: <5591D2EB.8050309@cran.org.uk> (raw)
On Linux, using the latest fio sources, "fio
examples/tiobench-example.fio" results in the progress indicator
(percentage and ETA) displaying odd values. Percentage rises to about
70% before dropping to 20%, getting to 25% and then the test finishes.
The ETA starts out about 4 minutes, falls to 1m and then jumps to 12.
$ ./fio examples/tiobench-example.fio
