Hi, I have a question regarding the speed of my program on linux in comparison to windows. I'm using geopy and contacting Google for geocodes for records in a csv I created. Like such: try: reader = csv.reader(open(filename, "r")) for row in reader: if row: # Checking to see if it's a valid row so it doesn't blow up on an empty row. username, address, address2, city, state, zip, country = row[0:7] location = address + ', ' + city + ' ' + state + ' ' + zip + ' ' + country try: place, (lat, lng) = g.geocode(location) # Contact Google for Geocodes I mainly use windows, but I tend to use Arch Linux at home. When I run it via windows, it's relatively slow and didn't really bother me, but when I ran it at home I got through 15 or so and got a message back from google saying I was exceeding the allowed amount. Or something to that effect. Basically, I was exceeding the 10 per second that's allowed. So, my question is. Why is it running so much faster on linux? Is it the way that linux is handling the socket? Does windows open and close it whereas linux might leave it open and just pump data through? It's not really a problem since I just added sleep time, but I'm curious. Thanks Tony ================================================================================== I think you might get a better response for this question on the main Python list. You say that at home you use Arch Linux, which implies you are running it from Windows in a different physical location. My initial thought is that your original run might have been from a location "far" from Google or with network congestion. Have you tried Windows and Linux from the same location? What version of Windows and Python for each? Not sure location should make *that* much of a difference though.
