Hi
As promised, I am supplying an example of comparison between several sort programs.
The test file is a randomly generated 1,000,000 lines, each line contain a single floating point number.
We are going to sort it three ways - as text, as -n numeric sort, and as -g numeric sort, with 4 programs:
1) Old BSD/GNU sort 5.3.0
2) New GNU sort 8.15
3) New BSD sort, single threaded
4) New BSD sort, multi-threaded
The system is a 3-CPUs system, 1.5Gb of RAM, FreeBSD version 8.2. All times are in seconds. Locale C.
==============================================
TEXT SORT
sys user real
Old BSD/GNU sort: 0.0 1.692 2.008
New GNU sort: 0.0 2.279 1.605
New BSD sort, st: 0.0 1.964 2.300
New BSD sort, mt: 0.0 2.385 1.897
==============================================
NUMERIC SORT -n
sys user real
Old BSD/GNU sort: 0.0 4.357 4.674
New GNU sort: 0.0 8.839 5.134
New BSD sort, st: 0.0 5.308 5.592
New BSD sort, mt: 0.0 4.581 2.489
==============================================
NUMERIC SORT -g
sys user real
Old BSD/GNU sort: 0.0 45.378 45.630
New GNU sort: ~450 ~121 ~300
New BSD sort, st: 0.33 4.334 5.992
New BSD sort, mt: 11.140 4.624 8.983
===============================================
Thanks
Oleg
