It might be a reference to OpenCRX's user accounts, not Firebird's.
Obviously if the index size limitation is a problem for their user
account name size. If that's the only limitation they have found, then
maybe FB 2.0 will make it in their recommended list. They seem to be
using Unicode, so if the user's account name is the person's full
name, then it is most likely that they defined it as more than 80
Unicode characters.

It would be nice if they would mention what are the issues that they
are having with views.

Personally, I wouldn't mind seeing views being precompiled, just short
of going through the optimizer, because of the indices stats can
change with the amount of data. And, when the view is being
referenced, the optimizer would generate the plan at that time.

Totally agree. They could at least make the recommendations on which
to use depending on the environment. Instead of saying that it's not
recommended for production.

Also, it's surprising that they also mention that Firebird's
performance degrade above 20 concurrent users.
