Delta load in data service 4.0

Hi,

We want to pull the data from ECC(6.0) to SQL Server 2008 using data services 4.0. We have used table comparison for the same. But the problem here is it takes lot of time to pull the data as it reads the data row by row.

Can anyone suggest how can we increase the performance of this job or any alternative for the same ?

Thanks in advance.

Regards,
