- Use more friendly output with GiB and MiB/s - Measure time per operation, providing finer grain stats - Add total stats for understanding system throughput - Add missing stats for flush I hope that these changes will help to understand and improve virt-v2v performance. Changes since v1: - Keep bytes values - Increase precision to 0.001 GiB and 0.001 MiB/s - Add total stats - Show time before

...nds, but elapsed time was 2.1 seconds. I think the missing time is in flush() which we do not measure yet. --- filters/stats/stats.c | 70 ++++++++++++++++++++++++++++++++----------- 1 file changed, 52 insertions(+), 18 deletions(-) diff --git a/filters/stats/stats.c b/filters/stats/stats.c index 6bef65c..2c92c65 100644 --- a/filters/stats/stats.c +++ b/filters/stats/stats.c @@ -62,6 +62,7 @@ typedef struct { const char *name; uint64_t ops; uint64_t bytes; + uint64_t usecs; } stat; /* This lock protects all the stats. */ @@ -80,28 +81,42 @@ calc_rate (uint64_t bytes, int64_t usecs) }...
