I worked for 5 years for SGI, a good portion of the time I was a Performer consultant. Very early OSG, in fact, was my first attempt to get a scene graph on Linux, before Performer was ported to Linux.
Much of what you will find in OSG is similar to Performer, as it has its roots there. The philosophies are similar as well, with OSG being a bit more extensible to handle evolving graphics software.
The multi-pipe harness is in Producer - which makes a bit of a departure from the Performer approach, but not entirely. If you think of Producer::Camera as a pfChannel, it will make some sense.
You will find quite a few ex-(some current) Performer users on this list, so please feel free to post the questions and expect good response.

I have a moderate sized (about 20K lines) OpenGL Performer (C++ / Linux) application.
With the future of Performer somewhat questionable, I would like to migrate this application

Does anyone here have experience/advice on porting Performer to OSG? Any thoughts
on level-of-effort? What features of Performer are not available in OSG?
Thanks,
