nr of ABAP import jobs

Hello

I performed an
export of a (ABAP cental) system and now I am performing import of same system.

For export of system 32 ABAP import jobs was  ideal.

I wander is 32 ideal (or »not so bad«) also for import?

Machine is same (Bl860c
i2 servers with 2 itanium processors (9300 series) 4 cores in hyper threading
each (so in total 16 hyper threading cores)

Thank you a lot in advance
