STAD results show DB req time greater than the response time
I am measuring the performance of RFC calls using STAD. After executing the RFC's (have been exposed as web services) I go to STAD and to my surprise the data base request time is greater than the response time (see below). How is this possible? Any help will be greatly appreciated.
Response time 4,177
Time in WPs 4,177
Wait time 0
CPU Time 2,609
DB req. Time 142,597
VMC elapsed time 0

sounds curious, but what hardware this system is running on? AMD CPUs? [Note 1036194|http://service.sap.com/sap/support/notes/1036194] describes a problem with CPU timers which could lead indeed to a similar situation as you described (parts of response time greater than the response time itself).
