Hi,
I have a question regarding the speed of my program on linux in
comparison to windows.
[snip]
Speed of a pure Python program depends on
* processor speed
* competition for resources from other processes
* perhaps RAM
A good starting point -create a benchmark program that uses only CPU -
no disk, no internet.
Example:
import time
n = 100000 # a guess
start = time.time()
for i in range(n):pass
print time.time() - start
Be sure n is large enough to create a run time of at least several seconds.
Run it on Linux and on Windows.
Do a speed check on your internet connections.
Then modify the program to open & read the csv file inside the loop. You
will have to reduce n when you add disk i/o
import time, csv
n = 10000 # a guess
start = time.time()
for i in range(n):
for line in csv.reader(open(filename, "r")):pass
print time.time() - start
