Is there a speed difference between python2.7 + mysqldb and python3.1 and myconnpy?
Hi Geert,
I am not sure where to post this, so I post it as a question, even
though it is more an answer ;)
We have a python3 based API with mysql backend using myconnpy...
And now we ported this to python2.7 (which was actually not that hard) and adapted our db-routines to mysqldb 1.2.3 (same functionality, same complexity of code, just mostly different syntax...).
Which enabled us to do a direct real life speed comparison :)
In a nutshell: python 3.1 with myconnpy yields the SAME speed than python 2.7 with mysqldb!
So if you can even optimize more we might end up getting even FASTER then mysqldb ;>
Here are the results:
Test: Select, modify, save one ~26k record 100 times.
Python 2.7 Server:
real 2m37.317s
user 0m0.450s
sys 0m0.120s
Python 3.1 Server:
real 2m33.375s
user 0m0.370s
sys 0m0.200s
Test: Select ~200 rows of ~200 bytes in length from one table, and
insert them into another table.
PYTHON 2.7 Server:
$ time python3.1 test4.py
