The user is likely to use this button in a firing motion by tapping the button.  On iPad2 , the frame rate drops considerably while tapping the play Button. However this is not due to the listener attached to the button.\r\n\r\nOne can recreate this issue by using the Demo Buttons on Sun, \r\n\r\n![sun demo screenshot 1](https://cloud.githubusercontent.com/assets/7633344/17681394/6b691c56-6313-11e6-86fe-c0bdf705bfb6.png)\r\n \r\nTapping the A, B C, D and E buttons , one can lower the fps to about 10-15 fps. (I guess i was tapping 5 times a second). Tapping the 1, 2, 3,4 buttons in the same conditions,  the lowest fps I could reach was 48 fps (a relatively decent result).\r\n\r\nThe ABCDE buttons using a 3DAppereanceStrategy whereas the 1234 buttons have a flat look.\r\n"},"comment":{"url":"https://api.github.com/repos/phetsims/sun/issues/comments/243166219","html_url":"https://github.com/phetsims/sun/issues/244#issuecomment-243166219","issue_url":"https://api.github.com/repos/phetsims/sun/issues/244","id":243166219,"user":{"login":"pixelzoom","id":3046552,"avatar_url":"https://avatars.githubusercontent.com/u/3046552?v=3","gravatar_id":"","url":"https://api.github.com/users/pixelzoom","html_url":"https://github.com/pixelzoom","followers_url":"https://api.github.com/users/pixelzoom/followers","following_url":"https://api.github.com/users/pixelzoom/following{/other_user}","gists_url":"https://api.github.com/users/pixelzoom/gists{/gist_id}","starred_url":"https://api.github.com/users/pixelzoom/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pixelzoom/subscriptions","organizations_url":"https://api.github.com/users/pixelzoom/orgs","repos_url":"https://api.github.com/users/pixelzoom/repos","events_url":"https://api.github.com/users/pixelzoom/events{/privacy}","received_events_url":"https://api.github.com/users/pixelzoom/received_events","type":"User","site_admin":false},"created_at":"2016-08-29T15:53:37Z","updated_at":"2016-08-29T15:53:37Z","body":"Any sim that has a fire button will involve frequently (more accurately, \"repeatedly\") tapping the button.
