I have a trace on a Windows 8 system that appears to replicate the issue.   The file loads in ~8 sec for release 2.0.0 and ~25.5 sec on master.  The initial load time with when the trace has apparently been flushed from the file I/O system cache adds an additional ~10 sec:  ~18.5sec on 2.0.0 vs ~34.5 on master.

I'm bisecting now.
