gcc 4.3的性能提升

zhuqin_83

Gcc 4.3.0 has been in testing for a while together with its related
toolchain updates (glibc, kernel-headers, binutils).

At this moment we've built OpenOffice.org for both architectures and
GNOME 2.22 for x86_64 with this compiler without noticable problems.
Produced binaries are roughly 5-10% faster than with the old compiler.

Tobias and I would like to have this one in core for the new release, as
the new kernel and all modules have been built with it also.

有谁测试过没？如果有5%-10%的提升，应当是很不错的。

编译Kernel通不过

xcxxb

编译出来的wine也基本不能用

没有用gcc4.3不过不知道是内核性能加强了，还是显卡驱动的原因，感觉桌面性能比原来好多了。大概也是gcc升级之后把。这次升级不知道如何

gcc4.2-4.3你说能有多大区别？只要你cpu不是那么最新的，支持什么sse4的，几乎没什么区别

刚编译了wine-0.9.58，没问题

这话好像是我说过的吧？

据邮件列表，core很有可能在iso和25内核正式发布之后rebuild。这下爽了。

Are we going to do a full core rebuild again?
We can do this on the road after Core Dump ISO with .25 kernel it is not
needed now.

哈哈..记性真好啊..
你之前说不要迷信这种小升级.现在见你也开始迷信了.所以把话贴回给你

我不是迷信，列表上maintainer是这么说的，那姑且信之。我也不过是猜测而已，5%-10%是什么概念，那人也只是感觉，说不定只是部分心理暗示。
