<b>DESCRIPTION </b><br>
|
||||
</dt>
|
||||
<dd><b> jsPerformance.pl</b> is normally used to run a series of
|
||||
tests measuring the performance of JavaScript against one of the JavaScript
|
||||
shells. The engine option above (-e) expects the JS shell to be
|
||||
in a peer directory. For example, if jsPerformance.pl is in a location
|
||||
like mozilla/js/perf/jsPerformance.pl, the engine option -e smopt will expect
|
||||
the optimized SpiderMonkey shell to be in a location like mozilla/js/src/WINNT5.0_OPT.OBJ/js.exe.
|
||||
If the JS shell is in a different location, this can be specified with
|
||||
the (-s) option, for example </dd>
|
||||
<dd><br>
|
||||
</dd>
|
||||
<dd> perl jsPerformance.pl -e smopt -s D:/JS_TRUNK/mozilla/js/src/WINNT5.0_OPT.OBJ/js.exe </dd>
|
||||
<dd><br>
|
||||
</dd>
|
||||
<dd>The timing results are displayed on the machine locally, peer to
|
||||
jsPerformance.pl. If no file name is provided using the (-f) option, then
|
||||
a time stamped file name is generated. The timing results are also sent
|
||||
to the server. The variable "$server" stores the value for the location
|
||||
of the server where the results are sent to. The following is a screen
|
||||
shot of the jsPerformance.pl, and highlighted is the variable "$server".</dd>
|
||||

<b>RESULTS</b><br>
|
||||
<dd><br>
|
||||
The picure below is a screen shot of
|
||||
a database that lies on the server. After the tests are run,
|
||||
it creates folders based on the JavaScript method you are testing.
|
||||
<img src="images/methodfolder.jpg">
|
||||
</dd>
|
||||
<br>
|
||||
<dd>Once the user clicks on the JavaScript method folder, inside are folders
|
||||
based on the machine specifcations based from the "config.txt"
|
||||
file which the user supplies. If a user does not provide a
|
||||
"config.txt" file, the timing results are sent to a default folder
|
||||
called "no machine specs!". <img
|
||||
src="images/folderspecslarge.jpg">
|
||||
</dd>
|
||||
<br>
|
||||
<br>
|
||||
<dd>After the user clicks on the configurations folder, the timing results
|
||||
are displayed like the following screen shot. <img
|
||||
src="images/timeresults.jpg">
|
||||
</dd>
|
||||
<br>
|
||||
<br>
|
||||
<dd>The first column lists the date and time the test was completed. The
|
||||
second colums lists the timing result for that method in miliseconds.
|
||||
In the third column is the JavaScript method that the user is testing.
|
||||
The fourth column is the IP of the computer which the test was run
|
||||
on. In the fifth column, are the configurations of the computer.

<b>TO DO <br>
|
||||
</b>
|
||||
<dl>
|
||||
<b><br>
|
||||
</b>This test suite is not finished. The JavaScript
|
||||
files have not all been created to properly test the performance of
|
||||
JavaScript.<br>
|
||||
<b> <br>
|
||||
</b>Currently the results are posted
|
||||
locally as a peer file to jsPerformance.pl, and to a server
|
||||
in directory-structure format. For example,<br>
|
||||
</dl>
|
||||
<dd> <img src="images/folder.gif" alt="[DIR]" width="14"
|
||||
height="12">
|
||||
Math.PI/ ---> win2k-1.7ghz-256mb ---> results
|
||||
of test</dd>
|
||||
<br>
|
||||
<dl>
|
||||
<br>
|
||||
in the "win2k-1.7ghz-256mb" file are the outputs shown:<br>
|
||||
<dd> 2002:10:25:17:49:20 4516 Math.PI 10.169.106.116 win2k-1.7ghz-256mb
|
||||
libwww-perl/5.65<br>
|
||||
2002:10:28:18:09:30 4531 Math.PI 10.169.106.11 win2k-1.7ghz-256mb
|
||||
libwww-perl/5.65</dd>
|
||||
<br>
|
||||
<br>
|
||||
and create another folder with:<br>
|
||||
</dl>
|
||||
<dd><img src="images/folder.gif"
|
||||
alt="[DIR]" width="14" height="12">
|
||||
Math.abs(-180)/ ---> win2k-1.7ghz-256mb --->results
|
||||
of test</dd>
|
||||
<br>
|
||||
<dl>
|
||||
<br>
|
||||
in the "win2k-1.7ghz-256mb" file are the outputs shown:<br>
|
||||
<dd> 2002:10:25:17:49:20 922 Math.abs(-180) 10.169.106.116 win2k-1.7ghz-256mb
|
||||
libwww-perl/5.65<br>
|
||||
2002:10:28:18:09:30 953 Math.abs(-180)
|
||||
10.169.106.116 win2k-1.7ghz-256mb libwww-perl/5.65</dd>
|
||||
<br>
|
||||
<br>
|
||||
<br>
|
||||
"Math.abs(-180)" and "Math.PI" may be replaced by "ABC" and "XYZ" which could
|
||||
be used as unique ID's that are assigned each time the
|
||||
test is run. <br>
|
||||
Everytime the test is run, it will generate a unique ID.<br>
|
||||
<br>
|
||||
The advantage of this is that you can just search for the unquie ID ("XYZ"),<br>
|
||||
and it will parse through all the folders and files...and look for that unique
|
||||
ID, and it will print it out like the following:<br>
|
||||
<br>
|
||||
URL: report.pl?id=XYZ<br>
|
||||
Math.PI win2k-1.7ghz-256mb 4531<br>
|
||||
Math.abs(-180) win2k-1.7ghz-256mb 922<br>
|
||||
<br>
|
||||
We would like to extend our testing to the CScript shell of Microsoft.
|
||||
However, the CScript shell may not support the
|
||||
-f option of the SpiderMonkey shell. Our test driver opens
|
||||
a process such as:<br>
|
||||
<br>
|
||||
D:/JS_TRUNK/mozilla/js/src/WINNT5.0_OPT.OBJ/js.exe -f ./tests/shell.js
|
||||
-f ./tests/boolean/valueOf-001.js<br>
|
||||
<br>
|
||||
Notice the first -f loads a file containing utility reporting functions:
|
||||
./tests/shell.js. <br>
|
||||
Only then is the testcase itself loaded: ./tests/boolean/valueOf-001.js.<br>
|
||||
<br>
|
||||
If the CScript shell has no analogue of the -f option a workaround will have
|
||||
to be found.
