Is JDBC connection faster than DB Link connection

edited Apr 23, 2012 2:47AM in Database Tuning (MOSC) 4 commentsAnswered
Team,

        We have two DB instances connected through 1G network. Instance A and instance B.
Instance B has table T1. We crearted db link between instance A and B and created synonym A:T1 that accesses
B:T1.

Our testing showed:
        Accessing B:T1 from machine A, through the synonym is around 10 times slower that accessing B:T1 from machine A using
JDBC connection.

Is DB links 10 time slower that JDBC connection?

Thanks,

Hisham
