separate fb_inet_server process for each successful connection. Each process has its own private page cache and, on 32-bit systems, can use up to 2 GB of RAM. • Superserver is a process named fbserver.exe threads for each successful connection request. All of these connection threads share a common page cache. On 32-bit systems, Superserver is limited to using a maximum of 2 GB of RAM. • In discussions, Classic nothing in it. For testing and deployment, the choice may be more important. Superserver's shared page cache, properly configured, can be beneficial for performance where many users are working concurrently

connection, each with its own cache. Less resource use if the number of connections is low. A single process serves all connections, using threads to handle requests. Shared cache space. More efficient if with FirebirdSS, Classic packages with FirebirdCS. For Windows, there is a combined installation package; you choose the architecture during the installation process. Embedded Server for Windows On Windows firebirdsql.org/pdfmanual/Using-Firebird_(wip).pdf (PDF) The Embedded Server comes in a separate download package. What is in the kit? All of the kits contain all of the components needed to install the Firebird

connec- tion, each with its own cache. Less re- source use if the number of connections is low. Single server process with a separate thread for each connection. Shared cache space. More efficient if the install Firebird. The Windows executable installa- tion script, the Linux rpm (RPM Package Manager, originally RedHat Package Manager) program and the official .tar.gz for other Posix platforms perform some rpm installs, consult the appropriate platform document- ation for instructions about using RPM Package Manager. In most distributions you will have the choice of performing the install from a command

chacune avec son propre cache. Moins de ressources sont utilisées si le nombre de connexion est faible. Un seul processus serveur avec un thread pour chaque connexion. Le cache est partagé. Plus efficace vous installez Firebird. Le script d’ installation exécutable de Windows, le programme rpm (RedHat Package Manager) de Linux et le fichier officiel .tar.gz pour les autres plates-formes Posix accomplissent rpm pour les installations, consultez la documentation de votre plateforme pour utiliser le RedHat Package Manager.

Client connections are handled by separate threads, each having their own database page cache. Other processes (e.g. embedded servers) may open the same database simultaneously (hence the Shared) server process with threads handling client connections. There is a single, common database page cache. The server requires exclusive access to each database file it opens (hence the Dedicated). Each
