Subject Firebird works.
I must admit that since I changed the connection mode from local to localho=
st:/, things start to work.
This way I can use the PHP pconnect´s which make it work as fast as Postgre=
SQL (with few clients, don´t tested high load performance).
May I ask why there is no a local connection way to avoid the evident overh=
ead of a network connection?

Thank you.
