julialangHow to measure execution time in JuliaLang?

Measuring execution time in JuliaLang is easy and straightforward. The @time macro can be used to measure the execution time of any expression. For example:

@time begin
    x = rand(1000, 1000)
    y = rand(1000, 1000)
    z = x * y
end

The output of the above code will be:

  0.001445 seconds (1.02 k allocations: 52.906 KiB)

The @time macro measures the total execution time of the expression, including the time taken for memory allocation. It also prints the number of allocations and the amount of memory allocated.

The @elapsed macro can also be used to measure the execution time of an expression. It is similar to @time but does not print the number of allocations and the amount of memory allocated.
