Is the button delay still an issue in JQM 1.1.1?

Is the button delay still an issue in JQM 1.1.1?

I'm using JQM 1.1.1, codiqa and AppMobi (similar to PhoneGap). I'm noticing some button delays/page load delays on iOS, and was wondering if the 300ms button delay is still an issue, or if there's something else I need to address. My app was partially made in codiqa. I have this set:

.ui-page > div {
      -webkit-transform: translateZ(0);
    }

        
        .ui-page > div
        {
            -webkit-transform: translate3d(0,0,0);
        }

I am also using no transitions.
Are there any further optimization tips?
