I'm doing a full export using the expdp tool. I'm using 4 dump files and parallel parameter with 4 value. The export size calculus shows 30Gb but it takes almost 4 hours for 4 Gb.
I'm pretty confused because i think it must take between 6 or 10 hours as maximum not more than 24 hours.
Is it normal than a 30Gb export takes so much amount of time ? Is it better to use exp instead of expdp in oracle 10g ?
