Komento SEO and Performance

Hi guys.
I am looking forward to buy Komento in order to integrate it with core Joomla Articles.

Currently we are using a setup based on a forum integration where for each article posted the system generated a forum topic for comments / discussion.
Comments "pages" (hence "forum topics" for comments) are indexed as separate forum pages by search engines.

We are thinking about switching to Komento to a more integrated solution and we have concerns regarding SEO and performance

Questions

1. How Komento performns with search engines: comments crawling, comments search engines indexing ... and so on. As i see comments are retrieved by Ajax, is this search engine friendly ?
2. How Komento performance is affected with huge comments number for a particular article ? Is performance comparable to a forum topic with huge number of posts ?


Thanks in advance !
