Performance between Django and raw Python
Depends on how your "plain Python" makes web pages. If it uses a templating engine, for instance, the performance of that engine is going make a huge difference. If it uses a database, what kind of data access layer you use (in the context of the requirements for that layer) is going to make a difference.
The question, thus, becomes a question of whether your arbitrary (and presently unstated) toolchain choices have better runtime performance than the ones selected by Django. If performance is your primary, overriding goal, you certainly should be able to make more optimal selections. However, in terms of overall cost -- ie. buying more web servers for the slower-runtime option, vs buying more programmer-hours for the more-work-to-develop option -- the question simply has too many open elements to be answerable.
I was wondering what the performance difference is between using plain python files to make web pages and using Django. I was just wondering if there was a significant difference between the two. Thanks
