ReadyApi 3.6.0 vs SoapUi PRO 5.1.1

Hello

I previously had a SoapUi PRO 5.1.1 program where a 6 steps TestSuite (included DataSource and DataSink) with 30.000 testcase run in 50 minutes.

At now I have ReadyApi 3.6.0 where the same TestSuite runs in 80 minutes

Why is it slower on the newest program?

I have 8 gb RAM and AMD Ryzen 5 PRO 3500u Processor and Windows 64 bit

Thank you
