Hmm....I don't see quite the disparity you do. Using your sample routines, I get:

IDL->about 40 msec
Python->about 37 msec

(These are "mental" means from running each routine a few times.)

IDL/Python versions:
-------------------Python
import sys

sys.version
Out[4]: '2.7.6 |Anaconda 1.8.0 (x86_64)| (default, Jan 10 2014, 11:23:15) \n[GCC 4.0.1 (Apple Inc. build 5493)]'

-------------------IDL

IDL> help, !VERSION
** Structure !VERSION, 8 tags, length=104, data length=100:
ARCH STRING 'x86_64'
OS STRING 'darwin'
OS_FAMILY STRING 'unix'
OS_NAME STRING 'Mac OS X'
RELEASE STRING '8.3'
BUILD_DATE STRING 'Nov 15 2013'
MEMORY_BITS INT 64
FILE_OFFSET_BITS
INT 64
