Sometimes people protest that they just don’t have time to benchmark the server for 8 or 12 hours at 10 different levels of concurrency on two or three server versions. If you don’t have the time to do the benchmarks right, any time you do spend is wasted; it is better to trust other people’s results, instead of doing an incomplete benchmark and getting the wrong answers.

The Cisco server has lower per-CPU performance than the EC2 servers. Surprised? We were a bit surprised ourselves.。。。Thus, the explanation for our results is probably as follows: the Cisco
server’s CPUs are a couple of years old, and are slower than the EC2 servers. But for
more complex tasks such as running a database server, the overhead of virtualization
places the EC2 servers at a disadvantage. It’s not always easy to distinguish between
slow CPUs, slow memory access, and virtualization overhead, but in this instance the
differences seem a bit clearer. (查看原文)

唯一读过的一个大部头的英文原版书,不仅学了技术,还学了英语。管理优化数据库,必不可少的案头书,特别是原理部分。

MySQL书籍中涉及方面计较全的,但是不够底层与详细
