README for ICU4C Performance Test
|
||
|
|
||
|
Introduction:
|
||
|
The performance tests in ICU4C compares various aspects of ICU against previous versions of ICU,
|
||
|
Posix, and/or Windows. Some tests only run on Windows and are labeled accordingly.All of the
|
||
|
performance tests are driven by a perl-based script which calls the underlying C program and
|
||
|
displays the statistical analysis of the test in an easy to read HTML web page. Each test will
|
||
|
have its own web page.
|
||
|
|
||
|
|
||
|
Requirements:
|
||
|
The most up to date tests are in ICU 4.0 and later. In addition, most tests depend on data which are
|
||
|
in a seperate repository.
|
||
|
|
||
|
Data repository:
|
||
|
http://source.icu-project.org/repos/icu/data/trunk/test/perf
|
||
|
There are 3 folders in here: collation, conversion, and udr.
|
||
|
|
||
|
|
||
|
Running Performance Test:
|
||
|
|
||
|
1) You should create a directory to hold the ICU (current and previous versions) and the data.
|
||
|
(e.g. C:\ICUPerformanceTest)
|
||
|
|
||
|
2) Checkout the current ICU and 2 previous versions (for proper regression testing) and the data
|
||
|
into the ICUPerformanceTest directory.
|
||
|
|
||
|
3) Do a general build on all the ICUs either through Visual Studios or with the Makefile.
|
||
|
|
||
|
4) Build the ICU performance tests either through Visual Studios or with the Makefile.
|
||
|
(The location of the performance test is: icu/source/test/perf)
|
||
|
|
||
|
5) Go to perf/perldriver and edit Common.pl.
|
||
|
In this file, you will need to set a few variables:
|
||
|
a) ICU version numbers
|
||
|
b) Path to the performance test data
|
||
|
c) Path to the root directory of the different versions of ICU
|
||
|
d) Whether or not you are running the test on Windows
|
||
|
* The Path needs to be absolute
|
||
|
* All other variables should be left as is
|
||
|
|
||
|
6) In the perf directory, there are several other directories for the various tests that can be run.
|
||
|
(e.g. convperf (Conversion tests)). Go to each directory and execute the perl script for each test
|
||
|
you want to run. (e.g. CharPerf_r.pl in CharPerf directory)
|
||
|
* You only need to run the perl script from the latest ICU version. The corresponding perl script
|
||
|
in the previous versions of ICU do not need to be run seperately.
|
||
|
* All of the test result web pages will be stored in perf/results.
|
||
|
|
||
|
|
||
|
Note: When running on Windows, cygwin is preferred.
|
||
|
Note: If a test needs to be run on Windows, a message will be displayed.
|
||
|
Note: After building the performance tests, it is a good idea to execute each C program to ensure that each
|
||
|
test can run. (e.g. convperf.exe)
|
||
|
Note: To run the actual performance test, you will need to setup Perl with the following modules:
|
||
|
a) Statistics/Distribution.pm
|
||
|
b) Statistics/Descriptive.pm
|
||
|
Note: Some tests take a while depending on the machine it is running on so a script to run each performance test's
|
||
|
perl script might be helpful.
