Springboot tomcat.threads線程數學習
摘要
壓測完nginx 突然想搞一下springboot內嵌的tomcat的 threads的參數
一不做二不休, 直接就着腳本進行學習和驗證
修改參數
產品裏面默認參數值是 500 我這邊改大一下
tomcat
threads:
max: 2000
accept-count: 10000
max-connections: 200000
connection-timeout: 600000
修改完後進行壓測
ab -c 5000 -n 50000 -k https://127.0.0.1:5401/index.html
ab -c 1000 -n 50000 -k https://127.0.0.1:5401/index.html
簡單結論
##注意不同測試測試, 結果不盡相同, 主要是看趨勢##
##本次測試取第二次預熱之後的##
threads 爲 500 時 1000併發
https 的吞吐量TPS爲:10260
第一次:4418.62
第二次:10260.98
threads 爲 500 時 5000併發
https 的吞吐量TPS爲:8701
第一次:3779.16
第二次:8701.95
threads 爲 2000 時 1000併發
https 的吞吐量TPS爲:11534
第一次:4982.65
第二次:11534.35
threads 爲 2000 時 5000併發
https 的吞吐量TPS爲:8267
第一次:3573.94
第二次:8267.08
threads爲500時 1000併發比5000併發性能要好.
threads爲2000時 1000併發比5000併發性能要好
1000併發時: threads2000比threads500性能要好.
5000併發時: threads500比threads2000性能要好.
感覺高併發下面. 500和2000的差異性不是很大,不會超過10%.
但是需要說明一下. threads2000時 會多佔用2G的內存. 用來存放堆棧信息
對機器的壓力會比較大一些. 進行容器或者是其他處理時需要關注一下這一塊的內存設置.
經過預熱和爲經過預熱性能差距是一倍多. 建議現場有機會還是需要預熱在上線.
或者是先小流量引入,再大流量進行使用. 保證TPS穩定.
