Curious as to who gave you that information?

To a large extent, CiviCRM will scale as well as MySQL will scale (which is the underlying DB that CiviCRM uses). There will be a few places in CiviCRM where we generate non-optimal (or in some cases awful) queries, but those are usually fixable fairly easily.

There are some large orgs currently using CiviCRM. From our pingback stats, we've seen multiple orgs hold more than 1 million contacts and more than 0.5 million contributions. Some large orgs that are currently using CiviCRM with large data sets include:

New York State Senate (lots of contacts and activities)
Wikimedia foundation, Concern International (lots of contributions)
Alpha International (lots of contacts and contributions)
Various political parties around the world

A data hosting company that has some open source programmers and reviewed our RFP as well as another vendor.  We are several months down the road with implementing Civicrm, but now working with a new hosting company.  I understand that everyone has their preferences and that alot of this is a matter of personal opinion or what you are use too. What I am really looking for is confirmation that Civicrm running on a mysql/drupal platform is running successfully with other large volume installations.  Within a year our goal is to have 1 million records within the contacts and generating 100,000 events a year. 

I am committed to Civicrm and believe it to be a valid solution. Is there actual track records or history of clients at this level using the system successfully? If so, are there requirements to successfully do that.

Thanks for the response.
