发现了gentoo的兄弟linux版本
注意不是yoper，这个版本和gentoo一起用的是pgcc（以一个补丁存在的gcc针对pentium优化的编译器可以比普通gcc编译的程序速度快30%），不过现在这个版本现在好象已经停了，据说是在孕量新的东西，他们会再返回的gentoo好象原来叫enoch，真是很怪的名字[url]http://www.stampede.org/[/url] 速度快30%不是经常可以达到的，那是intel的工程师达到的，一般只能达到5%，也许gzip可以达到25-35%:D 不过不要泄气，偶们也可以自己参看，然后自己多实验修改一下没准速度可以提高更多一些呢 [QUOTE][i]最初由 AIKO_sex 发布[/i]

我们在REDHAT上通过编译环境的修改重新编译程序，速度提高了几乎不止30%，很有效的。 gentoo转移到gcc3.1的行动正在开始,并且还有一项计划是用icc(intel c compile)来再次高度优化,可以 完全支持p4的优化People are finding our kernel to be quite zippy, particularly when it comes to interactive responsiveness -- something I care very much about. It's based on -ac so it has rmap and O(1) as well as some new IDE stuff. We've also added Robert Love's preempt patch, Andrew Morton's low latency code (both can be turned on/off in "make menuconfig" as desired) and bumped the HZ on i386 systems to 1000. Thanks to the efficiency of O(1) and rmap, HZ=1000 works nicely to increase responsiveness without introducing any significant overhead. And of course preempt does amazing things for interactive use -- much more so than low-latency. It's clear that good interactive response isn't *purely* about low-latency -- otherwise Andrew Morton's low latency patches would give much better and crisper interactive response, which isn't the case. Preempt seems to make the timeslicing of the CPU much more uniform (this is an educated guess, not a fact), which in turn appears to make a huge improvement in the "feel" of everything. It makes everything feel much more Amiga-like and presumably more BeOS-like.
Besides our performance-related improvements, we also now include XFS 1.1, htb2 (a very good QoS patch), grsecurity and a handful of patches from J?g Prante's bag of goodies, including freeswan (ipsec) and the international crypto patch (only available in our "crypto-sources" kernel which is an install option; our standard "gentoo-sources" kernel doesn't have any strong crypto so that people in countries where strong crypto isn't illegal won't break their country's laws unintentionally.) We also include Andrea Archangeli's 3.5Gb address space patch and a recent snapshot of the ACPI code being developed by Intel.
关于gentoo内核的特点,加入了低延迟,加大cpu分割时间段到1000的补丁(还有很多大概6-70多个吧),看起来和感觉有beos的味道
提供redhat和mandrake的内核,增加了服务器gentoo计划,稳定的服务器cvs树,用以区分开发版

gentoo好象原来叫enoch，真是很怪的名字[url]http://www.stampede.org/[/url] [/B][/QUOTE]
现在有个基于gentoo的方便初级用户的发行版在准备,getoo2.0的时候就可以了
