djpeg is not Emacs.  I just stepped through jpeg_load_body, and this
line takes about 1.5 sec for a 3 MB JPEG image:

  fn_jpeg_start_decompress (&mgr->cinfo);

Why don't you do the same (step with a debugger through that function)
and see where that time goes in your case?

Not here.  And I don't even have X.

Anyway, if in your case it's network related, prove it.
