Stéphane Nicoll opened SPR-13621 and commented
There is a major performance regression on annotations lookup in Spring Framework 4.2. We found out that a basic Spring Boot application was 10% slower between 1.2 and 1.3. We did some investigation and found out that a Spring boot 1.3 app based on 4.2 was also 10% slower than the same app on 4.1
One of the major hotspot difference is
AnnotationUtils.findAnnotation
. On 4.1 its own time is 23 ms (232ms in total) while on 4.2 it is 1,936ms (5,340ms in total)Affects: 4.2.2
