Many locks on AnnotatedElements ------------------------------- Key: HV-495 URL: https://hibernate.onjira.com/browse/HV-495 Project: Hibernate Validator Issue Type: Patch Components: validators Affects Versions: 4.2.0.CR1 Environment: GNU/Linux, JVM 6.0, Hibernate Validator 4.2.0.CR1 Reporter: Loïc DIAS DA SILVA Assignee: Hardy Ferentschik Fix For: 4.3.0.CR1 Attachments: jmeter-graph.docx, patch-ldds.patch Hi all, we use Hibernate Validator 4.2.0-CR1 (previously Apache BVAL) for one of our API projects. All is working fine for our needs except one big issue recently discovered during JMeter tests. Several injectors make many requests from some Amazon cloud servers to our API and starting from a number of requests the response time begins to increase eavily, making a big jump from about 100ms in average to more than 5s. After investigating we have seen many locks in some AnnotatedElement methods (mainly getAnnotation). I've then made a little patch on hibernate in order to cache this kind of requests as i've not found any other cleaver/yet implemented way.. Since this patch all is working very well for us.. Regards.
