johnyannj opened a new issue #1467: RuleExt （RandomRuleExt、WeightedResponseTimeRuleExt）中应该使用ThreadLocalRandom代替Random URL: https://github.com/apache/servicecomb-java-chassis/issues/1467 Random虽然是线程安全的，但是在多线程情况下会因为竞争导致性能下降。 javadoc： Instances of java.util.Random are threadsafe. However, the concurrent use of the same java.util.Random instance across threads may encounter contention and consequent poor performance. Consider instead using java.util.concurrent.ThreadLocalRandom in multithreaded designs
