Some tests only run on Windows and are labeled accordingly.All of the 12performance tests are driven by a perl-based script which calls the underlying C program and 13displays the statistical analysis of the test in an easy to read HTML web page. Each test will 14have its own web page. 15 16 17Requirements: 18The most up to date tests are in ICU 4.0 and later. In addition, most tests depend on data which are 19in a separate repository. 20 21Data repository: 22http://source.icu-project.org/repos/icu/data/trunk/test/perf 23There are 3 folders in here: collation, conversion, and udr. 24 25 26Running Performance Test: 27 281) Checkout the current ICU and 2 previous versions (for proper regression testing) and the data 29 into your local system. 30 312) Do a general build on all the ICUs either through Visual Studios or with the Makefile. 32 333) Build the ICU performance tests either through Visual Studios or with the Makefile. 34 (The location of the performance test is: icu/source/test/perf) 35 364) Go to perf/perldriver, copy Common.pl.template to Common.pl. 37 In this file, you will need to set a few variables: 38 a) ICU version numbers 39 b) Path to the performance test data 40 c) Path to the root directory of the different versions of ICU 41 d) Whether or not you are running the test on Windows 42 * The Path needs to be absolute 43 * All other variables should be left as is 44 455) Create a directory pref/results. All of the test result web pages will be 46 stored in this directory. 47 486) In the perf directory, there are several other directories for the various tests that can be run. 49 (e.g. convperf (Conversion tests)). Go to each directory and execute the perl script for each test 50 you want to run. (e.g. CharPerf_r.pl in CharPerf directory) 51 * You only need to run the perl script from the latest ICU version. The corresponding perl script 52 in the previous versions of ICU do not need to be run seperately. 53 54 55Note: When running on Windows, cygwin is preferred. 56Note: If a test needs to be run on Windows, a message will be displayed. 57Note: After building the performance tests, it is a good idea to execute each C program to ensure that each 58 test can run. (e.g. convperf.exe) 59Note: To run the actual performance test, you will need to setup Perl with the following modules: 60 a) Statistics/Distribution.pm 61 b) Statistics/Descriptive.pm 62Note: Some tests take a while depending on the machine it is running on so a script to run each performance test's 63 perl script might be helpful. 64Note: The perl script is only used in one version of ICU. When you run regression tests, 65 it is recommended to run the tests from the later version of ICU. 66
