Concurrent CDI Bean Loading
Since Payara Server 5.184
It is possible to concurrently load CDI beans and potentially speed up an application’s load time by enabling Weld’s Multi-Threaded Bean Loading feature.
|By default this feature is disabled for all applications on Payara Server, and enabled for all applications on Payara Micro.|
Concurrent CDI bean loading is configured on a per-configuration basis using the
set on the
cdi-service.enable-concurrent-deployment property like this:
asadmin set configs.config.server-config.cdi-service.enable-concurrent-deployment=true
It is possible to configure the number of pre-loader threads like this:
asadmin set configs.config.server-config.cdi-service.pre-loader-thread-pool-size=4
When configuring the number of the pre-loader threads, use a sensible value that is consistent with the number of CPU cores available for the server instance, otherwise this setting may introduce performance degradation on the deployment times.
|Concurrent deployment of CDI Beans is enabled by default with 2 preloader threads in Payara Micro.|
|There are no equivalent configuration views for these commands in the Web admin console. They’ll be reserved for a future release|
