> Performance Regression in bean resolution in EAR files
> ------------------------------------------------------
>
> Key: TOMEE-4112
> URL: https://issues.apache.org/jira/browse/TOMEE-4112
> Project: TomEE
> Issue Type: Bug
> Components: TomEE Core Server
> Affects Versions: 9.0.0.RC1
> Reporter: Jonathan Gallimore
> Assignee: Jonathan Gallimore
> Priority: Major
> Fix For: 9.1.0
>
> Time Spent: 50m
> Remaining Estimate: 0h

> This is an interesting regression:
>
> If a component in the webapp part of an EAR-based application performs a
> lookup programmatically to a CDI bean, and that bean belongs to the EJB part
> of the EAR application, there is some interesting behaviour:
>
> The InjectionResolver is wrapped by a WebappInjectionResolver. This will
> attempt to lookup by type in the webapp bean archives. If the bean cannot be
> resolved here (because it is part of the EJB module), WebappInjectionResolver
> will then look it up in the parent (which will succeed).
>
> InjectionResolver caches the lookups, but doesn't cache lookup failures
> (previously it did). The impact is that each time the lookup happens,
> WebappInjectionResolver will attempt to resolve (and fail) the bean in the
> webapp archives first, without looking at the cache.
> This can lead to a significant performance issue, depending on the number of
> beans in the archives. I have measure it as 1000 TPS vs 60000 TPS.
