Performance and Scalability

To whom it may concern;

As I have looked, I have not been able to figure out the following about the OpenScholar project. So I apologize if its already been posted elsewhere, and please point me out to such links if the discussions are available:

1. Caching: Is there any reason why the Memcache module is not included with the OpenScholar project? Given that it isn't initially installed it makes me wonder if there is a problem with introducing Memcache to the project at a later stage. This also raises concerns about the eventual site ran by OpenScholar running into load issues due to the hits on the server.

1a. This also raises a question of: is there any reason why OpenScholar base does not use the PressFlow version of Drupal? This would introduce a layer of caching, scalability and performance that can be turned on/off depending on the requests and visitors to the site when the Admin decides it is necessary.

1. no_anon: Another one of is there any reason why it is not included? I do know for this particular module as it is considered in 'development', however it allows for the server hosting the OpenScholar project to stop generating cookies for all the visitors unless they are logged in, thus taking some load Off of the server.

I know there are a lot of 'Is there any Reason' questions here, and I apologize once again if they have already been answered. I basically want to know if there are any known repercussions to installing these modules down the road on top of the OpenScholar install.

Thanks,
Jason
