Higher scores indicate more serious performance issues.
Scores are weighted by invocation count (so a non-inlined hot method called 50K times will have a higher score than one called 20K times).
Currently branch prediction failures are weight as 50% as important as hot method inline failures:
From org.adoptopenjdk.jitwatch.suggestion.AttributeSuggestionWalker:
scoreMap.put(REASON_HOT_METHOD_TOO_BIG, 1.0); scoreMap.put(REASON_UNCERTAIN_BRANCH, 0.5);
Issues with less than 1000 invocations are not reported.
