Automatic Extensionless Mapping - Startup Performance Issues

[RohdeSchwarz-SDC]

Problem

As soon as I enable the feature jakarta.faces.AUTOMATIC_EXTENSIONLESS_MAPPING the webserver starts really slowly!
Maybe there is something you (or we) could do?

Setup

• Tomcat 10.1
• OpenWebBeans 2.0.27
• Jakarta Faces 4.0.8 (Mojarra)
• PrimeFaces 14.0.5

Logs

I'm not an OpenWebBeans user but as far as I can see
on their github repository you should use OpenWebBeans 4.0.2

How big is your webapp?

How big is your webapp?

It's a good question. How many XHTML files are there? Biggest bottleneck is in the ServletRegistration#addMapping() and the performance is servletcontainer impl dependent.

OWB has got nothing to do with this. Under the covers ServletContext#getResourcePaths() and ServletRegistration#addMapping() are being used which are part of the Servlet API.

[RohdeSchwarz-SDC]

How big is your webapp?

It contains ~ 100 *.xhtml files, but only ~5 are "toplevel" files, the rest are <ui:composition> to be included via <ui:include>.
I tried to rename those ~95 to *.xhtml.composition but it did not improve the procession performance of PostConstruct/PreDestroy annotations.

My impression is that com.sun.faces.spi.InjectionProviderFactory.createInstance scans the webapp's classpath twice for bean annotations like @Named?

[RohdeSchwarz-SDC]

Tried the same setup with alternative Jakarta Faces Implementation -> MyFaces

Same result 🤔

Can anybody reproduce this behaviour?

[BalusC]

As said,

Biggest bottleneck is in the ServletRegistration#addMapping() and the performance is servletcontainer impl dependent.

Rather try a different servlet impl instead of a different faces impl.

Can anybody reproduce this behaviour?

Haven't tried yet.

I would try with Java 21.0.5 and Tomcat 10.1.33 to see if it improves

Already running on Tomcat 10.1.33 and Java 23

[pizzi80]

I've tested on a "Playground" webapp with ~150 copy pasted xhtml files
and there is no visible overhead with extensionless mapping true or false

• Java Oracle 21.0.5
• Tomcat 10.1.34
• Weld 5.1.3.Final
• Eclispe Jersey 3.1.9
• OmniFaces 4.6
• Jakarta Faces 4.0.8 (Mojarra)

The average startup time on a Core i5 12th gen is 2,400 milliseconds (2,4 seconds)

the tomcat startup process use all the cpu cores...
from the first post I see that your startup time is over 10 seconds even with extensionless off
which is a lot of time for a frontend only webapp,
which cpu are you using?

[BalusC]

Norepro. Stale issue. Closing off.
