EchoPerformance

Print the timing and memory used to evaluate an expression

Contributed by: Wolfram Staff

ResourceFunction["EchoPerformance"][expr]

prints the absolute number of seconds and memory in bytes used to evaluate expr and returns expr.

ResourceFunction["EchoPerformance"][expr,label]

prepends label to a printed expression.

Details and Options

ResourceFunction["EchoPerformance"][expr] uses Head[Unevaluated[expr]] as label.

ResourceFunction["EchoPerformance"] has the attribute HoldFirst.

Evaluate an expression and print the time it took and the memory used:

In[1]:=

Out[1]=

Use a custom label to print performance data:

In[2]:=

Out[2]=

AbsoluteTiming gives the time it takes to evaluate an expression:

In[3]:=

Out[3]=

MaxMemoryUsed gives the maximum number of bytes used in evaluating an expression:

In[4]:=

Out[4]=

EchoPerformance prints the same performance data:

In[5]:=

Out[5]=
