HI,
looking at the output from darktable it seems your the masked modules
are a lot faster than on my system. Which version of darktable do you
use? Your demosaic and defringe are comparable to mine, the others are
just significantly faster so we didn't really paid a lot of attention to
them.
The numbers from time (real, user, sys) are just the the total runtime
(real) and the amount spend in the application (User) and the time spend
in the operating system (sys). The last two are the sum across all
cores, so having 8 cors calculate 1 second will result in 8s in user-time.
The time from 9.5 to 17.8 is almost the same for me and I think it is
the time needed to compress the png (but I don't know ;) ).
Regards,
Holger

command from your email :
$ time darktable-cli 2019-11-23T23_23_35+0100_7871.arw
2019-11-23T23_23_35+0100_7871.arw.xmp
2019-11-23T23_23_35+0100_7871.png --core --library :memory: -d opencl
-d perf 2>&1 > dt_log.txt
Although it took less than 18s, I’m not to understand the other numbers :
real0m17.835s
user0m48.886s
sys0m3.417s
And from the log it created I have :
9.516693 [dev_process_export] pixel pipeline processing took 8.120
secs (37.632 CPU)
17.805166 [opencl_summary_statistics] device 'AMD Radeon Pro 580
Compute Engine' (0): 295 out of 295 events were successful and 0
events lost
Does this mean it took 17.8 - 9.51 just to write the png file on the
disk ?
I find in my case that by far the 2 modules that used the most power
were demoniac and defringe. Not sure why this does not seem to be the
case for others… Apart from those 2, yes tone curve 3 and exposure 1/2
were slightly higher that the others…
CPU and GPU were reasonably loaded while exporting but not 100%.
Full log is attached.
I’d be happy for someone to enlighten me on these results :)
