Performance Of the Site

Hi all I am working on site on which i am planning to put around 1 billion nodes, 1 million term, 300 module enabled, 10 subdomain using domain module, Site Load donot know, its depend on users logged in (may be 100,000 at a time),10-20 Different Themes for users and so on.

Now I had Achieved 3 million node, 100,000 term, 178 module, 3 sub domain , 10 users , 3 themes. For these i put APC and i did indexing and database tunning.

After I installed phpAccelerator on my server I'm receiving from time to time 500 Internal Error. Any idea why?

Thank you!

Hi,
I wonder, how much can I scale Drupal? How can it be done?
I mean, can it Support 50,000 users with 20,000 using it concurently. In that respect, can it build site like LinkedIn with milions of users?
If it does scale up as CMS can it also be used as development framework to build heavy proprietary applications that are used by such large number of usres?

Thanks,
Gili

Hi All,

I am planning to order a virtual dedicated server service plan from APThost.com but I have just found that they do host porn sites with their services. I am wondering if this will affect google's indexing for my site. Please share with me your experiences if you have used their services before. Recommendation of other hosting companies also welcome. (I like apthost.com because they offer very good price and also read some good comments on their services from other rating websites)

Thanks =)
