Comment 4 for bug 1631720

Enventualy I found out what my problem was - and it was complex

My Usage of Sikuli
    I call Sikuli from Power Manager which enables me to Schedule events to be done
    After the update to Sierra the typing speed was 5 times slower than before
    (i.e. Test Script Typing 10 lines of rubbish into textedit 1min 25 Seconds - run direct 20 seconds)
    Sikuli was called using a command script
    After working with "Power Manager Support" I found that calling Sikuli using Applescript resolved the issue
