14<P>collperf is a test program for comparing collation performance and key lengths of ICU, Windows native collation
15and Unix/POSIX collation. It operates on a file of lines (names, for example), and performs one of three tests:</P>
16
17<OL>
18	<LI>Sort Key generation. Report on key lengths and key generation times.
19	<LI>Binary search. Report the average time required to look up each of the names (file lines) from the file in
20	a sorted list of all of the names.
21	<LI>Quick Sort. Report the time required to sort the file in memory, using the C library qsort function. The file
22	order is randomized prior to the sort.

36-help                  Display this message.
37-file file_name        utf-16 format file of names
38-locale name           ICU locale to use. Default is en_US
39-langid 0x1234         Windows Language ID number. Default 0x409 (en_US)
40                       see http://msdn.microsoft.com/library/psdk/winbase/nls_8xo3.htm
41-win                   Run test using Windows native services. (ICU is default)
42-unix                  Run test using Unix strxfrm, strcoll services.
43-uselen                Use API with string lengths. Default is null-terminated strings
44-usekeys               Run tests using sortkeys rather than strcoll
45-loop nnnn             Loopcount for test. Adjust for reasonable total running time.
46-terse                 Terse numbers-only output. Intended for use by scripts.
47-french                French accent ordering
48-norm                  Normalizing mode on
49-shifted               Shifted mode
50-lower                 Lower case first
51-upper                 Upper case first
52-case                  Enable separate case level
53-level n               Sort level, 1 to 5, for Primary, Secndary, Tertiary, Quaternary, Identical
54-binsearch             Binary Search timing test
55-keygen                Sort Key Generation timing test
56-qsort                 Quicksort timing test</TT></PRE>
