Time	Guideline Value	Problem Indicated	Seeing
Dispatcher wait time (Wait time)	<10% of response time <50ms	General performance problem with many possible causes
Load time (Load + Gen time)	<50ms	Program buffer too small or CPU bottleneck	C2 – Monitoring Hardware, DB, SAP Basis
Roll-in time, Roll-out time	<20ms	SAP Roll buffer or SAP extended memory too small or CPU bottleneck	C2 – Monitoring Hardware, DB, SAP Basis C8 – Memory Management
Roll wait time	<200ms	Problem with frontend communication (together with higher GUI time), or with communication with external component	C4 – ABAP and Java Programs Performance C6 – Interface C7 – SAP GUI and Internet Connect
