• graphics_times significantly slower in MacOS 10.13 with IDL 8.6

    From Ken G@21:1/5 to All on Sat Dec 16 07:22:58 2017
    In a nutshell, a few years ago I used to get

    |GRAPHICS_TIMES performance for IDL 8.1:
    | OS_FAMILY=unix, OS=darwin, ARCH=x86_64
    | Sun May 6 17:01:11 2012
    0.0912898=Total Time, 0.017483336=Geometric mean, 4 tests.

    Now, on a much more modern Mac laptop, and the latest IDL and MacOS, I get.

    |GRAPHICS_TIMES performance for IDL 8.6.1:
    | OS_FAMILY=unix, OS=darwin, ARCH=x86_64
    | Sat Dec 16 07:21:48 2017
    0.783545=Total Time, 0.16847334=Geometric mean, 4 tests.

    It's ten times slower. Does anyone have any suggestions about this?
