I hope you end up running amd64 on Intel(R) Core(TM) 2 Duo because you can get another 10 to 15 percent improvement that way. :) -Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Just swaping operating system build for amd64 gives some 10% ~ 15% gain. It's a gain that enables inserting a small site into the same box. I like to do my own tests, so I ignore the published ones. But a quick google search shows the same I stated above: http://www.scribd.com/doc/363677/Benchmarks-AMD64-in-32bit-mode-vs-64bit-mode-Ubuntu But how I told, we have real world fact with LAMP + cakePHP, and not with Linux+(cherokee, apache)+Mysql+(django, pylons) etc --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

So we should go with amd64 for the faster mysql and easy memory upgrade. In a hurry we can get obscene RAM sizes. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Actually I don't know that all modern processors are x64, but it seems to me that the server ones are. -Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I think the primary difference is the amount of RAM that is supported and whether or not you have compatible software. With that said, all modern processors are x64 so you probably want to default with an x64 OS unless you need x86 for software compatibility reasons. -Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

In my experience, when it comes to database backed web applications, the application logic is seldom the bottleneck (unless, of course, you do a lot of numbers crushing). You should probably focus your optimization on your database instead, and not so much whether you should use psyco or pyrex to speed up your Python code.

amd64 vs x86 hosting
Hello people. This is our first project with python and django. We've been playing with this stuff but now with django 1.0 we are going to do Real Paid Work(tm) with it. Until now we are a PHP/cakePHP shop. One concern is speed. Right now we are not thinking about scale. Just raw speed, and get the bucks back from the dedicated hosting we are going to hire. One question: ¿amd64 or x86? we've got some bechmark claiming superior performance for amd64, both with python and mysql, but then we can not tune with psyco. We've taken a look at pyrex but we do not know even if we are shooting in our foot with any of these. ¿are these technologies useful for actual web app tuning? I would love to get some advice for CPU/web server combination. For example amd64/lighttpd, amd64/cherokee, fastcgi etc...
