Unrelated to the individual or combined size, a large number of files causes a noticeable download performance hit. This can be further exacerbated by other factors, e.g. a somewhat slow or unreliable internet connection. During download, it may seem as if the web player stopped responding / working, whereas in reality it is actually still downloading files in the background and should eventually start. I'm not sure what to make of the mentioned browser crashes -- the web player / web experiments do not actually run "in" the browser and it crashing would not affect the browser.<br/><br/>Things that can be done to improve the situation are:<br/>- Reduce the amount of files involved (if possible).<br/>- Reduce file sizes as much as possible.<br/>- Download the set of files in smaller subsets by using &lt;batch&gt;. This might seem a bit hack-ish, but should actually work well. I've laid out that approach in some detail here: <a href="https://www.millisecond.com/forums/FindPost19616.aspx">https://www.millisecond.com/forums/FindPost19616.aspx</a><br/><br/><br/>Hope this helps.<br/>Mon, 24 Oct 2016 11:35:48 GMTDave
