Как решить, как решить проблему с производительностью, используя инструменты потоковой передачи в Mule?

2017-02-17 22 views
3

Я использую Anypoint Studio 6.1 и Mule 3.8.1 и имею рабочий процесс, который не работает, поскольку мониторинг потоков выглядит так, как и большинство активных потоков 250 max, которые не используются, даже если поток вызывается 250 одновременными пользователями в бесконечный цикл из JMeter 3.1.Как решить, как решить проблему с производительностью, используя инструменты потоковой передачи в Mule?

Я использовал инструменты, такие как VisualVM и YourKit, чтобы исследовать проблему и попытаться определить решение. Похоже, что большинство потоков припаркованы или ждут, но я не уверен, как вы собираетесь найти оптимальное решение производительности из дампов потоков и инструментов анализа?

Что показывает YourKit, когда вы смотрите на горячие точки? – rgoers

ответ

Описание проблемы не кажется правильным. Вы упомянули, что «похоже, что большинство активных потоков 250 max не используются». Это проблема? Если обработка достаточно эффективна, чтобы отвечать на все запросы с меньшим использованием ресурсов, чем максимально допустимое, то почему это будет проблемой? Вам нужно будет уточнить, есть ли у вас какая-то актуальная проблема, связанная с этим.

Резьбовые дампы в основном используются для поиска проблем с блокировкой резьбы или значительных отрезков в некоторой задаче. Для проблем с производительностью было бы лучше использовать профилировщик, такой как YourKit или более ограниченный в VisualVM. Опять же, вам нужно более четко определить проблему, чтобы узнать, что является правильным инструментом для использования.
