title: TStream.Position compared to TStream.Seek
body: <p>To move the "current byte" pointer in TStream class we can use property Position (e.g. MyStream.Position := 0) or using Seek method (e.g. MyStream.Seek(0, soFromBeginning). The question is, which one is more efficient (aka faster)? (I don't have the source, so I could not check it myself).</p>
  
  <p>So far I always use Seek in positioning that said pointer.</p>
