小伙伴们，你们有没有遇到过这种诡异的情况：服务器CPU不到30%，内存还剩一大半，可接口就是慢得像蜗牛，动不动就超时，用户投诉电话被打爆？压测的时候更气人——QPS死活卡在300，调线程池参数调到头秃，核心线程数从50改到500，最大线程数从200改到1000，队列容量从1000改到10000，结果QPS反而降了，真是越调越废。

If you live in an apartment, dorm, or a duplex, you probably have set quiet hours. Ignoring these can come with angry neighbors or warnings from the landlord. But it's not always easy on Saturday night when belting out Britney Spears karaoke songs to keep track of the time. Instead of getting a knock on your door at 11 p.m., set your speaker or the TV to automatically lower the volume at a set time. Your party will automatically get the memo that it's time to wind down.
