积极的业绩表现和预防措施
原标题:activemq performance gotchas and precautions

我将首次在我的一个项目中(用于持久信息的主题)使用积极的性别调查。 我读到,耐用电文可限制每秒电量。 我应了解哪些其他因素(例如,消费者缓慢),这些因素限制了活跃分子的规模和业绩特征,应当密切监测哪些衡量标准,以及所有热点损失的价值。

目前,我并不期望在“积极、积极、积极、积极、积极、积极和积极”中推动每秒1 000多起事件。

这里是几条ti。

  • increase your systemUsage limits from the defaults
  • increase your JVM heap size from the defaults
  • if using KahaDB, consider setting enableJournalDiskSyncs to false (helps throughput dramatically) or preferably use the new LevelDB
  • learn about producer flow control and consider disabling (frequently done)
  • consider using virtual topics (instead of durable topic consumers)
  • learn about prefetch-limit and tweak as needed

我与活跃的多指标类集调查讨论两个具体问题:

(1) 每一组人都有需要调整的记忆限制。 积极运动赢得一席之地,除非你们改变政界。 因此,你需要制定<条码>-Xmx,并改变会议名称,以使用更多的记忆。

2) 相对于第1号,在达到限额时,即为sender/em>(客户)区块。 在较新的版本中,有一个避免这种情况的氛围,而是提出了例外。 见rel=“nofollow”http://activemq.apache.org/producer-flow- Control.html
