'''User-mode sampling:'''
includes only for this current program and is for testing code efficiency (regardless of other processes)
'''Hardware event based sampling:'''

The CPU effective graph indicates how many threads the program used and it's poor,ok, and ideal performance segments can be adjusted to match the desired utilization in terms of max number of threads used at anytime ( and anything over ideal would be considered over-utilization).
[[File:Bottom-up.png]]
The CPU time is also displayed here and the brown section indicates how much each (sample rate) section used the CPU in terms of % of total utilization of the program.
