oh that is *fast* :-O
Last year I had one of my fits of obsession about performance and began experimenting with Dreamhost's FastCGI interface for the Rev CGI. It was complicated to set up, and for all the reasons you noted here at the time it was very complicated to write for.
So instead I decided to set it aside and go back to the straight CGI interface to see if I found any serious bottlenecks. I found none, and the clarity of writing for a non-persistent process kept everything simple. I added a reasonably simple token file+cookie scheme for persistent data when needed, but for most uses I don't even need that, and with or without that it's been quite speedy.
On the desktop the engine loads faster than most other apps, and on the server - without needing to initialize the GUI -- it loads about as fast as a server can pull its mere 2.5 MB executable up from the 7200 RPM disk.
I've not done much in the way of formal testing because I haven't yet found a good means of accounting for sever/transfer latency as distinct from the Rev process itself. But the server-side testing I've done shows the CGI engine running at speeds better than on my Mac (not surprising; Dreamhost uses some good systems), and the subjective experience of the overall throughput has been quite satisfying for myself and my site's visitors.
