javascript - $(document).ready or window.onload for hiding/showing a video -

i'm running script (hack) trick safari correctly sizing video on responsive page. script below waits moment hides, , shows video, causing safari realize should expand video proper size. i'm worried $(document).ready may fire script (i.e., before video loaded), causing script not supposed video. possible $(document).ready script may fire since video isn't loaded after set milliseconds video not hidden/shown? should use window.onload (or method?) instead ensure hide/show sizing hack works? in tests, script works, on reloads when clear cache. few times when i've loaded page on random computers video not size correctly until reload page. using window.onload seems less ideal in user may notice incorrectly sized video while page content loading, or see hack in action after does. <script> $(document).ready(function() { $("#video1").delay(3000).hide(0, function...

c# - Does using Async programming paradigm improve performance all time -

this question has answer here: does async , await increase performance of asp.net application 5 answers i started read docs , blogs .net async programming model. in documents says use async if operation blocking work(access file system, access network, access sql etc. remote data storage (if have more examples blocking works please share them) ). what if system has enough power run works without using async model. need still need async? i know don't waste thread calling blocking work, think have lots of free threads on threadpool. please threat question asp.net application perspective async (by async assume mean tap ) code not parallelization, not same of using threads thread pool offload other work. async makes more efficient use of thread; rather blocking thread while wait disk or network work, free thread else while waits disk or network finis...
