title: Files of text/plain type is transferred much faster than other mime types
body: <p>I have a HTTP file transfer java application.</p>
  
  <p>I have observed that text files (plain/text mime type) of higher size are transferred much faster than other binary files of lower size.</p>
  
  <p>In my client I am using Java script XMLHttpRequest to download the file.</p>
  
  <p>I first keep the file in a blob (browser memory) using response type "blob" and then save it to the file system by using a href.</p>
  
  <p>is there any specific reason of why this is happening. Is it because of the blob saving ?</p>
