chrome号称内存杀手不是盖的，不设设置的话，经常被它内存耗尽死机是常事。以下自用方法

1 自带的memory saver

chrome://settings/performance

Performance

Memory Saver
When on, Chromium frees up memory from inactive tabs. This gives active tabs and other 
apps more computer resources and keeps Chromium fast. Your inactive tabs automatically
 become active again when you go back to them. 

选项打开

另 chrome://flags/#high-efficiency-mode-available
还有其它实验选项，有兴趣可以看看

2,插件

OneTab

号称可省95%内存，可以尝试一下。
