    Hi,

    Thank you for the great plugin as it is working perfectly for the most part. However, while testing my site with PageSpeed, It is constantly highlighting “…js/autoptimize_ac1314d….js” under “Does not use passive listeners to improve scrolling performance” and “Reduce JavaScript execution time” on mobile specifically. Any Idea on how this can be fixed?

    the “passive listeners” are part of one of the original JS-files that AO is minifying and AO does not (and can not and should not) make those kind of changes to the JS ??

    re. execution time; the only _sound_ advice is to have less JS really. in pagespeed insights you can “drill down” on that recommendation and it should show if this pertains to the local (aggregated) JS or also to 3rd party JS (which is untouched by AO). that should allow you to assess the possible “damage” done by 3 party JS. If you want to know what local JS is hurting performance, you could briefly disable “aggregate javascript” and test with that configuration to see what javascript-files are listed as having a long execution time?

    hope this helps,
    frank
