RFC_GET_FUNCTION_INTERFACE very slow

Hi anyone,

We have problem with performace on portal when it makes a call on r/3 using JCO and JRFC to execute a RFC.

Scene: The problem occurs when the RFC is generated from portal

application via JCO.

The minimum execution time is 6 seconds. Two seconds to call JCO, three

seconds and half to execute RFC_GET_FUNCTION_INTERFACE (standard) and

DDIF and just 0,5 seconds to execute of the ZRFC that extract the data

on R/3.

In fact, we need to lower the time to execute

RFC_GET_FUNCTION_INTERFACE standard and DDIF.

There is no SAP Note or documents on SDN to fix this!

Any suggestion?

Thanks

Best Regards
