A data object, representing the times associated with a benchmark measurement.
A data object, representing the times associated with a benchmark measurement.
Returns an initialized Tms object which has u as the user CPU time, s as the system CPU time, cu as the children's user CPU time, cs as the children's system CPU time, real as the elapsed real time and l as the label.
# File lib/railsbench/benchmark.rb, line 430 def initialize(u = 0.0, s = 0.0, cu = 0.0, cs = 0.0, real = 0.0, l = nil) @utime, @stime, @cutime, @cstime, @real, @label = u, s, cu, cs, real, l @total = @utime + @stime + @cutime + @cstime end
An in-place version of add.
# File lib/railsbench/benchmark.rb, line 446 def add! t = Benchmark::measure(&blk) @utime = utime + t.utime @stime = stime + t.stime @cutime = cutime + t.cutime @cstime = cstime + t.cstime @real = real + t.real self end
Returns the contents of this Tms object as a formatted string, according to a format string like that passed to Kernel.format. In addition, format accepts the following extensions:
%u |
Replaced by the user CPU time, as reported by Tms#utime. |
%y |
Replaced by the system CPU time, as reported by stime (Mnemonic: y of "s*y*stem") |
%U |
Replaced by the children's user CPU time, as reported by Tms#cutime |
%Y |
Replaced by the children's system CPU time, as reported by Tms#cstime |
%t |
Replaced by the total CPU time, as reported by Tms#total |
%r |
Replaced by the elapsed real time, as reported by Tms#real |
%n |
Replaced by the label string, as reported by Tms#label (Mnemonic: n of "*n*ame") |
If fmtstr is not given, FMTSTR is used as default value, detailing the user, system and real elapsed time.
# File lib/railsbench/benchmark.rb, line 501 def format(arg0 = nil, *args) fmtstr = (arg0 || FMTSTR).dup fmtstr.gsub!(/(%[-+\.\d]*)n/){"#{$1}s" % label} fmtstr.gsub!(/(%[-+\.\d]*)u/){"#{$1}f" % utime} fmtstr.gsub!(/(%[-+\.\d]*)y/){"#{$1}f" % stime} fmtstr.gsub!(/(%[-+\.\d]*)U/){"#{$1}f" % cutime} fmtstr.gsub!(/(%[-+\.\d]*)Y/){"#{$1}f" % cstime} fmtstr.gsub!(/(%[-+\.\d]*)t/){"#{$1}f" % total} fmtstr.gsub!(/(%[-+\.\d]*)r/){"(#{$1}f)" % real} arg0 ? Kernel::format(fmtstr, *args) : fmtstr end
Returns a new 6-element array, consisting of the label, user CPU time, system CPU time, children's user CPU time, children's system CPU time and elapsed real time.

Same as format.
