Thanks for the welcome :)
You're right. Here's with the missed line (I was cutting out commented
parts). Hopefully these are all cut/paste-able.
#test A
#runs in 5.8 seconds.
from datetime import datetime
testvar2='9a00'
startTime = datetime.now()
filehandle=open('testwriting.txt','w')
for var in range(10000000):
filehandle.write(testvar2)
filehandle.close()
print (datetime.now() - startTime)
#test B
[using '9.00' -- otherwise identical]
I do use the same filename, but I've run the tests in different orders
and it's made no difference. Repeatedly running the same test results
in the same numbers with only minor fluctuations (as would be expected
from cache issues). Ten runs in a row of Test B all result in about 11
seconds each. Ten runs in a row of Test A all result in about 6 seconds
each.
I could not reproduce this. You've got better hardware than mine,
certainly (I had to remove a 0 to get reasonable times) but I got almost
identical results with both versions. I've tested also with 3.0 (and I had
to take another 0 off!) with the same results.
I have no idea why you see a difference. Unless the antivirus is
interfering, or you have some crazy driver monitoring disk activity and
the dot triggers something...
Try using a different language - I'd say this is totally unrelated to
Python.
