> Our team upgraded our application (>205 modules) from WFLY 8.2.1 to WFLY 17.0.1 we experienced a noticeable slowdown during the deployment process (3min vs. 6min)
> A colleague found out that the following classes seem to cause the lag during dependency resolution since dependencies are processed multiple times:
> * weld/subsystem/src/main/java/org/jboss/as/weld/deployment/BeanDeploymentArchiveImpl.java
> * weld/subsystem/src/main/java/org/jboss/as/weld/deployment/processors/ExternalBeanArchiveProcessor.java
> and came up with the following workarounds that should fix the issues

> The fixes should prevent dependencies from being processed multiple times, however, the latter should be improved.
