Vtiger doesn't scale well, and all of our sponsors for the integration found that out in different ways. At high record counts it becomes incredibly slow even if you throw very high-end database hardware at it. Vtiger's method for managing custom fields is extremely inefficient, and the coding was done by about a dozen different programmers using several different methods to do the same thing, and sometimes within a different framework(PHP, Templating, Javascript, etc...) making the core code very difficult to work with.
In the end, two of the companies moved to Vicidial's custom list fields, and the third company developed their own custom CRM solution that integrates with Vicidial.
