Do you have more than the default labels here?  I saw max 10ms (first draw) 
and more like 2ms usually, but that was for plain labels.  (are we parse 
limited, or X limited on your machine...)

No.  It draws *3* times.  The first is very fast (~10ms).  The 2nd, which 
doesn't show, is ~950ms.  The third, which shows is ~350ms.  From the command 
line is ~350 ms.
