Slow response time HTTP=>XI=>RFC

[Former Member]

I have a HTTP call to XI BPM which makes a sync RFC call to another SAP system via SA bridge. The BPM is working fine. However, the time taken to process a transaction is about 6 seconds (not much data – about 2 lines).

The party initiating HTTP call is not satisfied with this response time.

Their current system (C program to SAP via API/RFCs) take about a second to respond.

Here’s how my response time is distributed based on the WF analysis of the steps

InfoLink_To_SAP_BPM urn:abc.com:InfoLink Workflow started 4s

Start Message: Receive XML from InfoLink

Initialize System Element

Mapping Step completed 0s

Process control record read in XI

Send Message Synchronously Step completed 1s

Mapping Step completed 0s

Send Message Synchronously Step completed 0s

Mapping Step completed 0s

S/A Bridge: Response to Synchronous Request 1s

It seems like the first step takes 4 sec. Does it take this long for HTTP connect? Or is this to launch or initialize WF / BPM?

In SAP, the RFC look .0027 secs to complete.

Does anyone have any idea on how to improve my response time.

Thanks!

Hi,

In a BPM with sych-asych bridge we did observe a 3 -4 sec processing time, its just initialization time on the workflow.

when we approached SAP Workflow team, we were told that was the optimal time. Unless something has changed in the new SP packs!!

Naveen,

You are right, it seems like WF takes time to initialize. Do you know of any parameters we can tweak in to make it any better.

FYI - We are on SP14.

thanks.

Hi,

There is nothing we can do. As per the SAP workflow team that response time is the best they can.

may be in the coming SPs they may imporve the time

cheers,
