不走系统缓存直接读写磁盘？嘛，虽然硬盘本身还有缓存，但是实在不能理解禁用缓存是什么心理……嫌硬盘命长……？要不就是这译文本身词不达意- -

不知道，默认第一个勾了，第二个没勾

防止意外关机导致文件损坏

以前的emule经常这样，现在没了

新选项？

--- 2008-01-01: Version 1.8 alpha (build 7435)
- Feature: options to bypass Windows disk cache

至于这两个选项是干什么的
F1看帮助
Disable Windows Caching of disk writes disables Windows\' native caching of writes to disk. This option helps when the Windows disk cache sometimes causes an extremely large amount of physical system memory to seemingly \"disappear\" while µTorrent is downloading quickly (because it is trying to cache µTorrent\'s increased disk writing rate). When memory becomes fully used, page swapping occurs, which can cause slowdowns. On the other hand, enabling this option may cause increased disk seeks, which may decrease transfer rates when the µTorrent disk cache is full.

Disable Windows Caching of disk reads disables Windows\' native caching of reads from disk. This option helps when the Windows disk cache sometimes causes an extremely large amount of physical system memory to seemingly \"disappear\" while µTorrent is uploading quickly (because it is trying to cache µTorrent\'s increased disk reading rate). When memory becomes fully used, page swapping occurs, which can cause slowdowns. On the other hand, enabling this option may cause increased disk seeks, which may decrease transfer rates when the µTorrent disk cache is full.

是不是一个概念不重要
重要的是的英文原文和帮助文档里面对应的解释
论坛上也有管理员的解释
When your disks can\'t really keep up, the Windows system cache steps in and starts caching it. Eventually, it\'ll probably eat all your RAM.
So be warned, you can save your RAM by enabling the bypass, but speeds might be reduced.
网速不快的不用勾这两个
除非网速快到硬盘来不及读写

那啥，如何定义网速快？

回复 #10 yang0079 的帖子

下載速度比你硬盤緩存還快

相对硬盘写入速度快
一般至少也得10mB/s以上吧
国内个人用户一般来说是不需要勾选这两个选项的

tonyunreal 发表于 2008-9-15 03:38

看上面的英文解释，我怎么觉得关掉才容易丢失数据呢……
文件碎片多到一定程度的时候读取速度不到1m/s也见过

aaaa007cn 发表于 2008-9-15 15:11

这是防止物理内存被windows缓存占掉太多吧，不是防止丢失数据
不过就算低到1m/s，国内大多数人网速还是够不上的啊
