Under package SWDP_PERFORMANCE_VERIFICATION there is a pair of reports WDT_TRACE_ON and WDT_TRACE_OFF which could switch on and switch off performance trace.
To switch on trace, set the user parameter WDA_PERF_TRACE_ON as abap_true, then run report WDT_TRACE_ON.
You can find all positions where framework has done such performance recording with the help of report RS_ABAP_SOURCE_SCAN with search keyword name = macro name wdr_perf_trace_on and search package name = SWDP_RUNTIME_CORE.
