Pandas runs so slow when get option data
I'm using windows server 2003, and python2.7 with pandas 0.16.2. It takes my computer 4-5 minutes to execute the following program:

---

from pandas.io.data import Options
aapl = Options('uso', 'yahoo')
data = aapl.get_all_data()
print data.iloc[0:5, 0:5]

---

Is it ok or not? 

If anyone wants to know more details, please let me know.

Thanks
