p:ajax faster than f:ajax ( PF 2.1 )

[ghagleit]

Hi there ,
i noticed something strange today.
Here is the code:

Code: Select all

<h:selectOneMenu id="semModeSel2" value="#{announcement.holdingSemester}" rendered="#{announcement.managed}" disabled="#{announcement.disableHoldingMode}" valueChangeListener="#{announcement.holdingModeChanged}" >
    <f:selectItems value="#{announcement.semestersSelection}" />
    <p:ajax event="change" process="semModeSel2" update="globalMessagesPanel" />
</h:selectOneMenu>

Basic idea: User changes the value, if condition met show message.
When i am using f:ajax this takes about 500ms BUT when i am using p:ajax this takes about 250ms!!!
Another thing i noticed p:ajax doesn't execute the preRenderViewEvent ( which is good ) f:ajax does.

Can somebody try to reproduce or has a explanation why this happens?

Using PF 2.1 SS and MyFaces 2.0.2
best regards

Unlike 1.1., PF 2.2 uses standard server side apis for ajax so it should be same. Not sure where the difference comes from.
