I do not have _NT_SYMBOL_PATH defined as a system variable.

Regarding renaming symsrv.dll, it does produce interesting behavior. I
rename the file to symsrv.dll.hide, start VS and the initial run of the app
in the debugger now executes CreateInstance in 12 secs instead of 45.
However, the second time I run the app (without shutting down VS), I'm back
to 45 seconds every first time I run the app in the debugger. If I shut down
VS, start it up again, and run the app in the debugger, it's back to 12 secs
the first time I run the app in the debugger, then it's back to 45 seconds
every subsequent first time I run the app in the debugger.

Even if I could get it to run 12 secs every time, it's still unbearably
slow. Any other ideas?

Here is the 12 second output:
