90%的項目都不需要調優，除非是達到了京東天貓級別的網站訪問量和併發量，其他的視情況而定，一般都是自己的代碼問題，能優化代碼的儘量優化代碼
啓動優化：

能看到啓動的時候就進行了兩次FullGC，
想要優化就是儘量減少FullGC的次數，GC的時間和次數足夠少，
第一次FullGC的情況：
[Full GC (Metadata GC Threshold) [PSYoungGen: 7142K->0K(75776K)] [ParOldGen: 32K->6991K(89600K)] 7174K->6991K(165376K), [Metaspace: 20527K->20525K(1067008K)], 0.0226215 secs] [Times: user=0.11 sys=0.00, real=0.02 secs]
第二次FullGC的情況：
[Full GC (Metadata GC Threshold) [PSYoungGen: 9828K->0K(196608K)] [ParOldGen: 7079K->14796K(138240K)] 16908K->14796K(334848K), [Metaspace: 33872K->33872K(1079296K)], 0.0363551 secs] [Times: user=0.09 sys=0.00, real=0.04 secs]
能看到Metaspace也就是元空間，同時也能明顯的看到YGC的針對元空間來的
先記錄一下第一次沒有調整前的啓動時間：
2020-04-26 01:57:12.178 INFO 3884 — [ main] com.sxj.seed.SeedApplication : Started SeedApplication in 3.176 seconds (JVM running for 5.618)
然後對元空間進行一個調整：
增大元空間
-XX：MetaspaceSize=64m
再次啓動：

能看到已經沒有FullGC了，並且YGC也沒有針對元空間進行回收，啓動時間也縮短了，同時也能看到GC的次數減少了，只有三次了，
再優化一下，設置起始堆的大小：-Xms1000m
啓動：

能看到GC是在啓動後在才GC，但是這樣已經可以了，在設置就沒必要了，已經足夠了
運行優化:
在運行時進行優化就需要藉助jemter壓測工具了
添加參數，查看單線程SerialGC工具的使用情況:-XX:+UseSerialGC
查看多線程的GC情況：-XX:+UseParNewGC
