which is close, but I recall a slightly more detailed treatment. Can anyone point me to a fuller treatment of the performance impact of an 11.00 32-bit upgrade and/or share a personal experience of same?

Consider what applications you will be using. If the application is tuned for 64 bit, then use the 64 bit HP-UX.
Running a 32 bit app on a 64 bit OS _will_ cause a performance degradation.
I personally have seen HP-UX 11 run slightly slower on older 800 & 700 series machines, but unable to see difference on newer systems, like a K580 or D390. N-Class of course only run 64 bit 11.
Hope this helps!

We keep in our company an extra HP9000/847/G30 mashine for experiments. I've installed on it both 10.20 and 11.00 for the same purpose - performance comparison. Find attached to this massage the output from /opt/ignite/bin/print_manifest for detailed description of the system.
There is obvious performance degradation in running the same applications on 10.20 and 11.00. You can see this even when use some basic HP-UX utilities such sam and swinstall.
I don't have benchmarks to send, but if you want further details or you can suggest experiments to carry out just tell me

While it still maybe slower at some things (sam, sd-ux), the overall system calls are very fast (with the latest patches).
The only way to be sure if it's fast enough for you, is to benchmark it.
Hope that helps.

Try the attached Kernel parameters from a 10.20 9000/800/K580 server. It is the current kernel that I have for my oracle 8.0.5 applications and we don't have performance problems. Apply the parameters applicable to your systems's kernel (11.00).
