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 l'écriture des données asynchrone – ce qui permet de garder en mémoire cache les nouvelles données ou modifications. La mémoire cache est vidée périodiquement sur le disque par le sous-système d'entrée sortie écritures forcées sur un serveur Windows. On a observé que les serveurs Windows ne vident pas le cache tant que le service Firebird n'est pas arrété. Indépendament des coupures de courant electrique, il
