That is of course a given for M:Ncpus (or any M:1 scheme) - assuming that M implies userland threads (ala linuxthreads).
It is due to the fact that linuxthreads are an M:1 scheme (M:Ncpu too?) that Firebird Superserver on Linux does not display the same problem. OTOH, this also implies that while Firebird Superserver on Linux will not give the problem displayed on NT, it is still also unable to take advantage of multiple CPUs.
Whoops... mea culpa... apparently Linuxthreads is a 1:1 scheme like NPTL. So the NT-specific problem that required setting affinity to a single CPU could lie in how NT does threads... and it would seem that Firebird on Linux _will_ take advantage of multiple CPUs.
