I am testing an Android app which sends minute-by-minute updates to my Drupal site which acts as a server.

I create a single node each day and all my app data is saved in CCK fields within that node.

I got the updates working yesterday and tested for half a day. When I try to edit the node, to see the CCK data uploaded, my site crashed and complained of lack of PHP memory.

In my .htaccess file, I had set PHP memory to 100M. I then increased it to 300M and then 500M with no improvements. Then I tried 1000M. It worked but it seems slow.

That's just for one user's half a day's worth of data. Eventually, I will have hundreds of users with 24hours data each.

Can anyone tell me if there is a Drupal distribution which handles heavy data traffic by design?

    are you the only person testing your Drupal and do you need 1000M?. may be do you have some issue with your server/Drupal/App configuration. (sorry if I do not understand you)

    Sounds like you're using CCK fields for something they were not designed to be used for. An optimized distribution can't fix architecture problems. Commented Apr 3, 2012 at 15:18

You should have a look at Pressflow.

Pressflow is a distribution of Drupal with integrated performance, scalability, availability, and testing enhancements.

    PressFlow is a great distro, specially for D6, but I'd still think looking at your structure again would help you to prevent a lot of future frustrations.

Bojan put it right in a comment above. I just think its important to explain it again, in case someone finds this in the future :)

I think the problem here is rather in the design. If I get it right, you are saving all the data from 1 day into 1 node ?

When you attempt to load such one node, drupal loads all the data in memory, so I am afraid that no settings and distributions can save you, you just have to change the design - probably having 2 types - 1 for the day and 2nd for the data entries.

You might as well try something "lighter" for the data - such as the data module.
