Of course, one CPU doesn't mean 1-connection-at-a-time... My guess is 
you'd still need a fair number of simultaneous connections before one 
CPU became the bottleneck. Don't forget also that if you're running 
Firebird in Superserver mode, it'll only make use of one CPU as well.

Still, comparing database performance *in general* can be tricky. Some 
databases are better at some workloads than others, and vice versa. All 
you can do is compare them on the *particular* load your application 
creates. That does not (necessarily) mean your results are valid under 
ALL workloads.

Having said that, there's certainly no harm in doing the comparison.
