I still feel that the orange resource — Step 3a — is a potential bottleneck, so I schedule a two-day buffer before the potential bottleneck.

我仍然可以感觉到“桔红色”资源——步骤3——是一个潜在的瓶颈，所以我在潜在的瓶颈之前安排了两天缓冲时间。

The hit ratios for data and index pages reflect the number of times a page request was handled by the buffer pool directly without requiring disk I/O.

数据和索引页面的击中率反映了缓冲池在不需要磁盘 I/O 的情况下直接处理一个页面请求的时间量。

youdao

Transactions requiring disk I/O, such as flushing dirty pages from the buffer pool or flushing logs from the log buffer, may wait.

要求磁盘 I/O 的事务，例如刷新缓冲池中的脏页或者刷新日志缓冲区中的日志，可能需要等待。

youdao

So I hit control X. It's very unnecessarily arcanely saying save modified buffer, and then answering no will destroy changes.

敲入控制键X，它会很罗嗦地,问你是否保存所做的修改,如果回答为NO，就不保存修改过的部分。

Whenever I share to Twitter, Facebook or any other place, Buffer tells me how many people clicked, liked, retweeted, favorite and more.
