[infinispan-issues] [JBoss JIRA] (ISPN-6062) Remove megamorphic calls when calling next method in interceptor stack

Remove megamorphic calls when calling next method in interceptor stack ---------------------------------------------------------------------- Key: ISPN-6062 URL: https://issues.jboss.org/browse/ISPN-6062 Project: Infinispan Issue Type: Enhancement Components: Core Affects Versions: 8.1.0.Final Reporter: Radim Vansa With current acceptor-visitor architecture of interceptor stack, calls to next interceptor use megamorphic interface calls. This is suboptimal as it prohibits the JIT compiler from inlining the calls. Since the interceptor stack is not changed very often, we may adapt the code programmatically to call next interceptor directly. The solution should verify that interceptor stack is inlined as much as possible with 'common' JVM options - increasing -XX:MaxInlineLevel is viable, while we should not request users to mess with -XX:DesiredMethodLimit. Preferably, -XX:FreqInlineSize and -XX:MaxInlineSize should stay at defaults.
