Stash performance degrades over time with Java 1.7.0_51

XMLWordPrintable

      This is related to Spring 4.0.0.RELEASE which was introduced in Stash 2.11.0. This only affects newer versions of Java 1.7.0_51 and greater.

      https://jira.spring.io/browse/SPR-11335

      Diagnose

      Taking a thread dump will most likely show many threads being stuck in Spring AOP:

      "http-bio-127.0.0.1-7990-exec-5" daemon prio=10 tid=0x00007f510c009800 nid=0x2456 runnable [0x00007f50768e2000]
   java.lang.Thread.State: RUNNABLE
    at org.springframework.core.SerializableTypeWrapper$TypeProxyInvocationHandler.invoke(SerializableTypeWrapper.java:220)
    at com.sun.proxy.$Proxy25.equals(Unknown Source)
    at org.springframework.util.ObjectUtils.nullSafeEquals(ObjectUtils.java:252)
    at org.springframework.core.ResolvableType.equals(ResolvableType.java:681)

      If profiling is enabled a clear indication is very slow getById() calls:

      [3914ms] - "GET /rest/api/latest/profile/recent/repos HTTP/1.1"
   [1128ms] - Repository com.atlassian.stash.repository.RepositoryService.getById(int)
