Front End network time and GUI time

[Former Member]

Hello,

I am having a few doubts on the performance monitoring of SAP servers.

GUI time - is the time taken for several communication steps between the SAP R/3 server and the local SAP R/3 frontend.

After this definition i have a few doubts.

1) what is the difference between, GUI time and front end network time?

2) While calculating the processing time do we substract GUI time from the actual respone time?

Please help.

Thanks.

Hi,

F1 help provides the exact information of the each time specified in st03n..

Further for your information:

Frontend time:

The front-end network time (FE Net time, fenettime, sometimes also called guinettime) is the time span that is consumed for sending data from/to the front end.

However, no roundtrips (RFCs) for the GUI are included. These are entered in the GUITIME.

If RFCs are involved on the server side, this time is specified with an incorrect value.

The FE Net time is formed by the difference that arises between the response time from the view of the frontend and from that of the application serve

GUI time:

The GUI time is the time used in the network and the local front end for these communications steps (not the time in the application server, however). The GUI time does not contain the front end network time.

Regarding the Processing Time:

Please Refer following note 8963.

For Response time Refer note 1063061 which gives clear idea of What is response time.

1) what is the difference between, GUI time and front end network time? 

GUI Time is response time between the dispatcher and the GUI during the roundtrips

The network time is the time used in the network during the first data transfer from the front end to the application server and during the last data transfer from the application server to the front end. It therefore does not include the u201Croundtripsu201D (communication steps during a dialog step).

2) While calculating the processing time do we substract GUI time from the actual respone time? 

Yes

I have 2 more questions now

1) If we substract Front end n/w time from GUI time (GUI time - Front end n/w time) do we get the round trip time?

2) Response time is defined as the time from which the dispatcher receives the request until the data is sent out to the front end..

 1) If we substract Front end n/w time from GUI time (GUI time - Front end n/w time) do we get the round trip time? 

Yes, you can check one of the record in STAD for more details. Here you will get no of round trips, GUI time and net time.

 2) Response time is defined as the time from which the dispatcher receives the request until the data is sent out to the front end.. 

Yes, but in ST03 you can get dialog response time without GUI time too.

Hope this helps.

1. The GUI time does not contain the front end network time.

2.Processing time: This is equivalent to response time minus the sum of wait time, database request time, load time, roll time, and enqueue time , so not subtract GUI time .
