Question by gaspardpetit · Jul 08, 2014 at 12:54 PM · textwebplayerwwwxmlslow

WWW requests are exponentially slow on large web pages (xml)

I have noticed that serving large web pages over the WWW class in a webplayer game becomes extremely slow.

I use the server to send custom assets as xml and sometimes they can take a few MB or even several hundred MB. The bandwidth starts high and decreases over time as CPU increases (even though I do nothing but yield for the WWW object to finish. It looks exactly as if Unity was doing something like this:

 while (isThereMoreData)
 {
   Download a bit of xml data
   WWW.text += aBitMoreText;
 }

Which, on large text data, would end up getting the text buffer moved and copied in memory as its size increases..

I have checked my http headers and they indicate the content size correctly, which means that the WWW object could pre-allocate the memory buffer.

Has anyone else experienced this and found a work around?

The UnityWebRequest class can be considered WWW 2.0 and I am pretty sure that it allows you to accomplish your goal.
