Predictive Analysis Performance Issue - with HANA

$

0

Hello,

 

Has anyone experienced slow performance on Predictive Analysis when using the HANA reader/writers?

 

Algorithms that usually take seconds with excel/csv are taking a long time with HANA. Ex. Multi-Linear Regression with a single independent variable on a small dataset (only 1000 records) is taking ~5 minutes to execute.

 

Is it normal that working with HANA from PA is slower than working with flat files?

 

Thanks in advanced for your help!
