I wrote a program by using Delphi 7 and it's database version FireBird
1.5. its working in LAN and WAN but. WAN connection is very slow i wait
approximately more than one minute to take data.

I use Delphi's InterBase components for FireBird connection. On the
TCP/IP connections to FireBird database, it working but its very slow.
Where is my mistake, what do you think about this problem ?

Thank you.
