最近打算用圣诞的时间把gentoo专门为我的笔记本做个从stage1的优化,HP的TC1000,CPU为Transmeta Crusoe。

昨天晚上的时候已经把系统做了个stage4的备份,还设好了diskless,想是不会出什么问题了。

几个地方还是不清楚,也没经验,弄过的还望不吝赐教:

1.从stage1开始都用专为Crusoe设的优化CFLAG编译是否真的可以大幅提高系统的速度?这是我在网上找到的CFLAG:

gcc 3.x -O3 -march=i686 -pipe -fomit-frame-pointer -mpreferred-stack-boundary=2 -falign-functions=0 -falign-jumps=0 -falign-loops=0

2.为了加快速度准备使用另外两台电脑做distcc,只要我在笔记本上带distcc运行emerge是否与完全在笔记本上编译出的代码一样?

3. 做完后想试试prelink。kde我是不用的,像firefox,evolution,apache,mysql,emacs是否通过prelink能加快速度呢?(gcc都是一样版本)

4. 想把系统优化前后做个比较,该用什么样的方法或软件呢?



做完后有时间的话也可以写个howto了,呵呵

沉不住气,自己顶一个
是没人弄过还是没意义呢?

我來支持一下!!

我想 這Crusoe 可能不是很多人在用, 其實除了 第一條那個 Crusoe中央處理器有點“嚇人”之外, 相信其它的都是大家很想掌握的技術。

找來一些文檔資源:
http://gentoo.linuxsir.org/doc/cn/distcc.xml
http://www.gentoo.org/doc/zh_tw/distcc.xml
http://gentoo-wiki.com/HOWTO_Distcc_server_on_Windows

http://www.gentoo.org/doc/zh_tw/prelink-howto.xml
http://gentoo.linuxsir.org/doc/cn/prelink-howto.xml


有其中任何一項的經驗嗎?還請大家都來分享一下。:)

distcc很方便使用,只要几台电脑的gcc版本一样就行了,都安装上distcc,按照手册的内容设置就行了。
程序的速度很难一概而论,就算你把这些都作好了,我来问你哪个快了,哪个慢了,你也不一定能明确回答。所以,加速是需要的,测量就不要期望了。
所谓比较,应该使用benchmark了,没有用过,不过gentoo上都有
app-benchmarks

关于获得最合适的 CFLAGS, 请试试 acovea, emerge 就可以 :)

八九小时? 你的机器够快噢, 我当时看谁的帖子说 acovea 运行一次就起码得 15 个小时什么的, 哇...

我的机子不快啊,crusoe TM5800, 1GHz,相当于800Mhz左右吧。只不过这次是用p3的设置测的,看来还要给我的cpu专门写个测试的config...

Linux啊,总是让我有事弄,在这一点上真的有点怀念windows了,装完一次就了事,除了偶尔有点安全漏洞,别的也不错 :twisted: :twisted: :twisted:

这就是linux的“魅力”吧 :P

不过起码每次问题解决后都有收获,启动到windows,总是会想到去玩玩游戏,哈哈~~
