| 14 <P>collperf is a test program for comparing collation performance and key length
s of ICU, Windows native collation | |
| 15 and Unix/POSIX collation. It operates on a file of lines (names, for example), a
nd 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 t
he 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, usi
ng the C library qsort function. The file | |
| 22 order is randomized prior to the sort. | |
