Type: Bug
Resolution: Obsolete
Priority: Major
Fix Version/s: None
Affects Version/s: 8.2.0.Final
Component/s: JSF
Labels:
None
Environment:

Windows 7 64 bit,
Oracle JDK 1.7.60 64bit,
Wildfly 8.2.0.Final
JSF 2.2

Steps to Reproduce:
Hide

Edit the standalone.xml in wildfly and disable weld (I disable it by removing the following two lines):

<extensions> .............. <extension module="org.jboss.as.weld"/> .............. </extensions> <profile> .............. <subsystem xmlns="urn:jboss:domain:weld:2.0"/> </profile>

Download my sample JSF project and deploy it (Its basically a JSF page with multiple components and an ajax button).

Send ajax requests multiple times and measure the response duration using an inspection tool (I used chrome inspection tool)

Repeat the previous steps with weld enabled and check the responses time difference

The ajax response time dramatically increases by increasing the number of JSF components when weld is disabled.

This doesn't make sense and I have no idea why does it occur

WELD ENABLED

WELD DISABLED
