原文:
Faster processors wont improve performance all that much; most Web servers spend up to 90% of their time waiting on disk I/O. As soon as you start swapping, performance will just die. Faster disks might help slightly, but theyre much more expensive than RAM, such that it doesnt really matter.
翻译:
高速的处理器并不会大幅度地提高性能;大多数的Web服务器90%的时间都浪费在了硬盘IO上。当硬盘上的数据开始交换,性能就急剧下降。更快速的硬盘可以改善这个问题,但是比起RAM来说,那太贵了。
