Per your request:
The handler:
query | avtime completed failed rps
-----------------------------------------------
single_print | 110 5000 0 881
here_print | 111 5000 0 881
list_print | 111 5000 0 880
concat_print | 111 5000 0 873
multi_print | 119 5000 0 820
-----------------------------------------------
The benchmark unbuffered:
single_print: 2 wallclock secs ( 2.44 usr + 0.31 sys = 2.75 CPU)
here_print: 4 wallclock secs ( 2.34 usr + 0.54 sys = 2.88 CPU)
list_print: 8 wallclock secs ( 7.06 usr + 0.43 sys = 7.49 CPU)
concat_print: 9 wallclock secs ( 8.95 usr + 0.66 sys = 9.61 CPU)
multi_print: 22 wallclock secs (16.94 usr + 5.74 sys = 22.68 CPU)
The benchmark unbuffered:
single_print: 1 wallclock secs ( 1.70 usr + 0.02 sys = 1.72 CPU)
here_print: 1 wallclock secs ( 1.78 usr + 0.01 sys = 1.79 CPU)
list_print: 7 wallclock secs ( 6.44 usr + 0.05 sys = 6.49 CPU)
concat_print: 9 wallclock secs ( 8.04 usr + 0.06 sys = 8.10 CPU)
multi_print: 10 wallclock secs (10.56 usr + 0.09 sys = 10.65 CPU)
The interesting thing is that list_print and concat_print are quite bad in
the benchmark but very good in the handler. The rest holds.
