Users experience very slow SAP GUI 7.20 application performance in an ICA session. The application screen is updated or refreshed with a significant delay that can reach over one minute. The behavior also occurs with the Citrix API hooks disabled and in an RDP+ initial application session.

SAP rectified some performance problems with patches available for the SAP GUI 7.20. For a XenApp 6 deployment, SAP GUI 7.20 is only supported by SAP at patch level 5 and above.

Problem Cause

The issue has been referred to SAP as a dump file analysis revealed that the SAP application threads put themselves into sleep state awaiting synchronization events for a long time.

Configuration recommendations for SAP GUI 7.20 to increase performance is available on CTX127399 - SAP GUI 7.20 Performance Issues and Graphical Distortion when Run in an ICA Session.
