1. How can I tell if an existing Firebird installation is configured/installed/running in Classic Server / Super-Server mode?
2. How can I switch between the two?
3. Which versions of Firebird and which architectures support multi-threaded applications on multi-processor servers?
4. How to configure Firebird on multi-processor servers?

re Q1:

Look for fbserver.exe (and potentially fbguardian.exe) in firebird_dir\bin fodler for Super-Server installations; and look for fb_inet_server for Classic Server installations.

re Q2:

doesn't look it's possible to "switch modes". Might have to uninstall/reinstall, or potentially install multiple instances (2nd install has to be done manually - not with the installer - refer to http://www.firebirdsql.org/rlsnotes/Firebird-2.1.3-Installation.pdf

still working on Q3 and Q4.

re Q3: Only Classic Server architecture supports multiple cpu's and there's a comparison chart here http://www.iblogmanager.com/download/misc/articles/fb25_architecture_comparison.pdf

re Q2: You can switch between modes by effectively uninstalling the service and reinstalling it with different parameters as Andrei advised here http://stackoverflow.com/questions/1926731/firebird-architecture

Here's the answer... (thanks Andrei)

Close all client connections. Got to Firebird\Bin directory. Execute specified sequence of commands:

instsvc stop
instsvc remove
then either:

instsvc install -s -a   -- for Super Server
or

instsvc install -c -a   -- for Classic
after that:

instsvc start
3 -- Super Server always runs on single processor or core and can not scale. Use Classic architecture in SMP environment. In latter case dont specify page buffers more than 800-1000.

Be aware that performance of Classic Server depends on performance of disk subsystem. For big databases use RAID controllers with internal cache memory, battery and "write back" mode enabled.
