I am using the Atmel ICE programmer to program an ATTiny84. Doing that from the Arduino IDE takes more than 10 seconds. Calling avrdude from the shell is 5x faster. How can I speed up Arduino IDE's programming?

This is on MacOS Sierra and it's the Atmel ICE (not the JTAGICE).

    Turn on verbose mode and compare the arguments to avrdude, as different clock rates may be being specified. Also be sure the same installation of avrdude is being used in both cases. Verbose mode should also let you see if the issue is actually download speed, or other things being done before that attempt is made. – Chris Stratton Dec 31 '17 at 21:14

    10 seconds is unbearably slow ? ... I think that you may have other issues that have nothing to do with programming – jsotola Dec 31 '17 at 22:56
