Hi,
I have a python script that uses Sqlsoup to iterate over some rows of table
to modify them. The script is running really slow and I ran cProfile to see
where is the bottleneck. I've got this:
20549870 function calls (20523056 primitive calls) in 34.800 CPU
seconds
Ordered by: cumulative time

504 0.003 0.000 3.138 0.006 sqlsoup.py:535(entity)
The problem is commit, almost all the time used by the script is on commit.
Is there a faster way to modify every row? Or Should i use raw sql?
Regards,
Diego
