Parallel Scavenge收集器

在這裏插入圖片描述

Parallel Scavenge收集器也被稱爲“吞吐量優先收集器”。

Serial、ParNew、CMS等收集器的關注點是儘可能縮短GC時用戶線程的停頓時間，而Parallel Scavenge收集器的目標是達到一個可控制的吞吐量（Throughout）。
吞吐量=用戶代碼運行時間/(用戶代碼運行時間+垃圾收集時間) 吞吐量 = 用戶代碼運行時間 / (用戶代碼運行時間 + 垃圾收集時間)
停頓時間越短就越適合需要與用戶進行交互的應用，良好的響應速度有助於提升用戶體驗；吞吐量越高就越適合在後臺運算而不需要太多交互的任務，良好的CPU利用率有助於儘快完成運算任務。
