我刚刚升级到emacs 24的最新git仓库并按照说明进行编译: http://www.emacswiki.org/emacs/EmacsSnapshotAndDebian
重绘时看起来相当缓慢,特别是在调整缓冲区时,无论是垂直还是水平。
我使用相当不错的硬件在1920x1080的两个屏幕上运行Ubuntu 10.04 64bit: i7-930,12GB DDR3内存,英特尔SSD X25M,Nvidia 8400GS 512MB DDR2。
调整窗口大小时,我注意到在尝试重新绘制屏幕时,一个核心最大值为100%。
在编译期间或我的系统中是否可以进行任何优化?
如果我有一个非常小的emacs窗口,那么它重新粉刷 我需要更快的显卡吗?或者这不是显卡问题,是emacs在后台做的事情吗?

Emacs 24有时会变慢。但它尚未发布。
您的帖子是2011/02年,这是一个旧版本。从那以后,很多都发生了变化。特别是,由于双向文本(bidi)的发展,显示引擎有很多非常大的减速。这些减速很大程度上得到了照顾。
结论:升级到最新的Emacs 24 prelease(#2)。
