[jboss-user] [JBoss Seam] - Re: DOCTYPE definition on *pages.xml performance warning/imp
I added some basic timing code to Pages.class for the following methods. Both call
getDocumentRoot():
| package org.jboss.seam.core;
|
| ...
|
| public class Pages {
| ...
|
| private void parse(InputStream stream)
| {
| long t1 = System.nanoTime();
|
| ...
|
| long t2 = System.nanoTime();
|
| System.out.println("pages1: handling = " + (t2 - t1) / 1000000);
| }
|
| private void parse(InputStream stream, String viewId)
| {
| long t1 = System.nanoTime();
| ...
| long t2 = System.nanoTime();
|
| System.out.println("pages2: handling = " + (t2 - t1) / 1000000);
| }
|
| ...
| }
My test is to define 2 simple pages that had a linked to each other. So clicking the link
should produce test output for request and response phases and hopefully show the cost of
parsing for a page transition.
Test 1: DOCTYPE was correct for verion 1.3 for pages.xml and test.page.xml - average time
spent parsing and processing *pages.xml for a request/response cycle was 48ms.
Test 2: DOCTYPE was set to 1.2 for for pages.xml and test.page.xml; running CVS Seam 1.3 -
average time spent parsing and processing *pages.xml for a request/response cycle was
958ms.
More detailed data is below:
Test 1: DOCTYPE was correct for verion 1.3
t1 -> t2
pages1: handling = 11
pages2: handling = 12
pages2: handling = 8
pages1: handling = 9
pages2: handling = 7
total: 47ms
t2 -> t1
pages1: handling = 9
pages2: handling = 10
pages2: handling = 15
pages1: handling = 11
pages2: handling = 9
total: 54ms
t1 -> t2
pages1: handling = 9
pages2: handling = 8
pages2: handling = 9
pages1: handling = 15
pages2: handling = 10
total: 51ms
t2 -> t1
pages1: handling = 9
pages2: handling = 12
pages2: handling = 7
pages1: handling = 9
pages2: handling = 5
total: 42ms

Test was done an a dual Xeon 2.8Ghz/2Gb RAM. App was warmed by navigating between test
pages 10 times before taking timings.
