Increase output to file speed #9

Closed nanowish closed 8 years ago

nanowish commented 8 years ago

Hello,

currently output to file (/get from buffer) in jpeg take between 4 and 7 seconds (with my K-5) and seem too long than write to SDcard when I take picture directly from APN. Any tips for increase write speed ? tested write in tmpfs, ssd, sdcard, connecting to USB2.0, USB3.0 ... the bottleneck seem to be from APN buffer to computer. When triggercord write the file can't do more.

tested with: pktriggercord-cli --model=K-5 -i 200 -t 1/2 -r 10 --flash_mode=Manual-RedEye --aperture=4.0 --reconnect -o fwritetest -f

pktriggercord-cli --model=K-5 -i 200 -t 1/2 --flash_mode=Manual-RedEye --aperture=4.0 --reconnect -o fwritetest -f

pktriggercord-cli --model=K-5 -i 200 -t 1/120 --flash_mode=Manual-RedEye --aperture=4.0 --reconnect -o fwritetest -f

pktriggercord-cli --model=K-5 -i 200 -t 1/160 --aperture=4.0 --reconnect -o fwritetest -f

pktriggercord-cli --model=K-5 -i 200 -t 1/160 --aperture=4.0 -o fwritetest -f

pktriggercord-cli -v
pktriggercord-cli 0.84.00

4-7 seconds for a jpeg? How long does it take to download a dng?

nanowish commented 8 years ago

Yes for a jpeg.

DNG take more time:

My tests also shoes the select buffer takes quite a long time. The errors are not "real" errors. It only means that we have asked the camera to switch to the buffer, but the camera is not yet ready. If I don't wait till the switch is successful I cannot download the image later.

I've modified the poll interval so I check the result of the buffer switch more often. It increased the speed a bit (maybe 5%) I'm afraid I cannot increase the speed more.
