If you are working with users across the globe you will be faced with performance complaints for your FIORI apps and web developments.
To analyze these user complaints you need to throttle you network speed so it is behaving like a far way computer:
- Lower bandwidth
- Higher ping response times
The applications you develop close to the server on fast network can become very sluggish when used by distant users. It is your job as developer to analyze this issues and to improve your design to have less roundtrips.
Network throttling in Chrome
The full details of Chrome network throttling can be found here.
- Open the developer tools with F12 and go to the Network settings
2. Select the No throttling and create a new profile:
3. Now select your profile:
Enjoy the new end user experience. Don’t forget to switch back to your normal speed!
One of the most irritating and annoying things in the basis area is when the network gives issues. For whatever reason.
This blog will give hints and tips on how to recognize network issues and options to analyze them.
SAP notes on network performance
Main OSS note is: 1100926 – FAQ: Network performance.
Main SAP wiki on network performance can be found via this link.
Detailed analysis notes:
Specific issues with application to database server issues:
Check if database is the issue, or network:
Network issues on Azure:
Check by ST06: start the LAN check by Ping:
Or directly via transaction OS01:
SAP GUI network issues
If the user is far away from the server, network issues can be cause of slow transactions for the end user.
SAP GUI slow connection can be set on creation of GUI entry, or by right clicking on the GUI entry and then selecting the network option:
FIORI and web developments
FIORI tiles and web developments might be slow with users further away from the server. If the application has many round trips built in the increase network latency will definitely kill the end user performance.

In some cases you need detailed information on TCP/IP ports for SAP. This blog will also refer to notes from SAP with regards to network issues.
TCP/IP ports for SAP
All ports for SAP are listed on the SAP help site https://help.sap.com/viewer/ports.
When is this list important?
- When you have to setup firewall rules
- When you are doing changes: for example, changing from http to https, installation of web dispatcher, switch towards SNC
