I guess there might be something related with active directory and firebird. I will explain why.

My application originally used DBF files. Some years ago I moved to firebird and then my customers began to migrate to the firebird version. Everytime a user migrates, the application works faster in the server and in the clients. But in the two cases where the server has active directory, the firebird version was slower than the DBF version.

Switching on write cache on the server, I found the reason of this difference on the server. But in client PCs, when there is active directory, the firebird version is slower than DBF version. That´s why I think there might be a reason related both with active directory and with firebird.

Maybe the problem is outside of Firebird and your application: have you considered checking the network: low throughput and/or high latency of the connection could have a big impact on the user experience.
