How to find network performance  



We will be getting a connectivity to customers system soon. We would like to analyze the network performance while accessing the system. Can anybody guide me so as how to measure the same?

Will GUI TIME in STAD transaction help?

Thanks in advance.

You don't have to worry about the network performance.

The data transferred for SAP GUI is hardly few Kilobytes.

if the hardware of server is good you wont have much problem at your end.

Hi Sanjay,

Time spent for network communication between the front end and instance is not included

(unless so-called roundtrips to the front end are taking place), although from an

end-user point of view this time might be significant.

Effectively, the application server sends information in chunks

to the front-end PC during so-called round trips. The time spent for a round

trip is called GUI time; this time is measured at the application server. GUI

time comprises time spans for network communication and the time needed to

generate the screen at the front end.

You stated it correctly that it can be seen throough gui times in statistical records. This corresponds to time spent for the communication between application servers and the front-end, and the time is caused by the network time as well as the time that is needed to process the data by the front-end PC.

Also, check for OLE_FLUSH_CALL in the RFC traces.

The high network time may be caused either by a high amount of data that has to be transferred over the network or by a slow network speed. To reduce the amount of data, you can activate the low speed connection. Enable the u2018Low Speed Connectionu2019 option particularly for WAN connections. See SAP NOTE 203924 (Section 5) for details.

The user may deactivate the new visual design to reduce the CPU consumption on his desktop PC or should upgrade the front-end PC. See SAP NOTE 203924 (Section 6) for details.

YOu should also use ST06 --> Detailed analysis --> Lan check by ping for checking on the network traffic conditions.

Hi ,

Can you please tell us the way to identify the network time as " high".

Kindly provide us the general path for the OLE_FLUSH_CALL RFC trace.

Also, I have noticed a much crude way of identifying the network problem.

If we execute a transaction on the PRD server itself, it is not taking much time.

But if we execute the same transaction on a PC on the network , it is taking too much time

compared to other time. The cause may be due to the delay in the network.

Please provide your suggestions.

Hi Ram Krishna,

I have few points which may help you:

You can calculate the networktime using following fomular.

excerpt from SAP NOTE 578118.


networktime = (no_of_bytes)/(throughput) + (no_of_round_trips)*(RTT)

Please see the NOTE 578118.

Regarding throughput and RTT time, you can get the time via executing NIPING on your side.

Perform a Network Diagnosis with NIPING - SAP NOTE 500235

Long response times on the SAP GUI#    - SAP NOTE 578118

And check the SAP GUI front end patch level of the PCs connected to your SAP network.You can upgrade the patch level which may resolve this FE time.

Thank you,
