11 my $bench = Dumbbench->new(
12 target_rel_precision => 0.005, # seek ~0.5%
13 initial_runs => 20, # the higher the more reliable
14 );

23 This class inherits from Dumbbench::Instance and implements
24 benchmarking of strings of Perl code using "eval """.
25
27 new
28 Constructor that takes named arguments.
29
30 In addition to the properties of the base class, the
31 "Dumbbench::Instance::PerlEval" constructor requires a "code"
32 parameter. The "code" needs to be a string that is suitable for passing
33 repeatedly to string-"eval".
34
35 Optionally, you can provide a "dry_run_code" option. It has the same
36 structure and purpose as the "code" option, but it is used for the dry-
37 runs. By default, a simple "eval" is used for this, so it's unlikely
38 you will need the dry-run unless you want to strip out the compile-time
39 overhead of your code.
40
41 code
42 Returns the code string that was set during construction.
43
44 dry_run_code
45 Returns the dry-run code string that was set during construction.

51 Benchmark
52
53 Number::WithError does the Gaussian error propagation.
54
55 SOOT can optionally generate histograms from the timing distributions.
