January 03 Windows 7 Beta 1性能测试 全面超越Vista/XPWindows 7 Beta 1性能测试 全面超越Vista/XP
作者: 上方文Q 驱动之家 Windows 7 Build 6956虽然只是个预测试版,但其性能已经让我们很满意,那么作为唯一的一个公开测试版,Windows 7 Beta 1 Build 7000又会有何表现呢? 具体测试项目有以下23个: 1、系统安装:安装操作系统所需要的时间 2、系统启动:从开机到桌面可用的平均时间 3、系统关机:平均关机时间 4、本地文件移动:在两块硬盘之间转移100MB JPEG图片文件 5、本地文件移动:在两块硬盘之间转移1MB到100MB不等的2.5GB文件 6、网络文件传输:从测试机向NAS设备转移100MB JPEG图片文件 7、网络文件传输:从测试机向NAS设备转移1MB到100MB不等的2.5GB文件 8、负载下本地文件移动:制作DVD ISO镜像的同时在两块硬盘之间转移100MB JPEG图片文件 9、负载下本地文件移动:制作DVD ISO镜像的同时在两块硬盘之间转移1MB到100MB不等的2.5GB文件 10、负载下网络文件传输:制作DVD ISO镜像的同时从测试机向NAS设备转移100MB JPEG图片文件 11、负载下网络文件传输:制作DVD ISO镜像的同时从测试机向NAS设备转移1MB到100MB不等的2.5GB文件 12、文件压缩:使用系统自带功能压缩100MB文件 13、文件压缩:使用系统自带功能压缩1GB文件 14、文件解压:使用系统自带功能解压100MB文件 15、文件解压:使用系统自带功能解压1GB文件 16、安装Office 2007:从DVD光盘安装终极版的平均时间 17、打开简单Word文档:10页、只有文字 18、打开简单Word文档:100页、图文混合 19、打开简单Excel文档:基本格式 20、打开复杂Excel文档:包含公式和图表 21、刻录DVD光盘:使用CDBurnerXP刻录Windows 7 Beta 1 ISO镜像 22、打开简单PDF文档:Adobe Reader 8、只有文字 23、打开复杂PDF文档:Adobe Reader 8、图文混合 此番测试照例使用Windows 7和Windows Vista SP1、Windows XP SP3进行对比(都是32位版本),但不进行基准性能测试,只考察实际应用性能,而且为了便于对比,略去具体成绩,只是简单地打分:表现最好的系统得1分、最差的得3分、中间的2分,最后计算总分,得分越低越好。 两套测试机配置如下: 1、高端机型:Phenom X4 9700 2.4GHz处理器、Radeon HD 3850显卡、4GB内存 2、低端机型:Pentium DC E2220 2.2GHz处理器、GeForce 8400 GS显卡、1GB内存 测试结果:
结论: 在高端测试机上,Windows 7有21个项目取得领先,只有Office 2007安装略逊于Vista,而DVD刻录和Vista不分伯仲;对比Vista和XP,前者表现更好一些,15次胜出,其中Office 2007安装还是最好的。 在低端测试机上,Windows 7也拿下了20个项目,只有100MB文件本地移动不如XP(但好于Vista)、负载下2.5GB文件本地移动不如Vista(但有好于XP),另外DVD光盘刻录和XP差不多(但好于Vista);对比Vista和XP,分别有11项和12项获胜,最终得分也只差了1分。 在经历了Windows Vista的痛苦积淀后,Windows 7真的有些让人爱不释手,不但功能更丰富,性能也有了显著的改善和提高。尽管只是个Beta测试版,但新系统已经给了我们足够多的惊喜,除了一些小的瑕疵甚至已经可以当作日常工作、娱乐用系统了。对于最终正式版,我们有足够的利用充满期待。 看完这些,我的建议是如果自己的xp的笔记本电脑还可以坚持,就等着widows 7的笔记本出来,争取跳跃过Vista一代的机器,祝你现在的机器好运啦! January 01 文字处理N久没有更新博客了,终于在09年元旦发现一些有意思的东东得以更新一下^_^ 还有啦,最重要的是祝亲爱的你们元旦快乐,在09年里面充满平安和喜乐! May God Bless Your Way! 老风格,继续转载,一个关于文字处理软件的文章,文章作者是经历了全部手写到用计算机的各种软件写自己文章的过程。庆幸的是我们只经历了其一半,从其第五点开始到最后第八点。 Default file formatsBy Prof.Gelman source:http://www.stat.columbia.edu/~gelman/blog/ I was going to write that I used to write articles in Latex and now I write them in Word (for some examples, see here), and then speculate about how the change in format might change how and what I write. But then I thought that more background could be useful. 1. The pencil-and-paper era. Back when I was a kid I used to write everything by hand. I was proficient with the eraser. In high school I developed a style where I'd outline the English composition first and then write it. 2. Typewriter. In college we had to type our papers. Which I did, using my little typewriter (which had been my sister's before that), until . . . 3. Mark's homemade word processor. My college roommate was a CS major and had an Atari computer. I persuaded him to write a word processor in 6502 assembler, and I ended up using it more than he did. I took a couple of English classes that required a paper every week or so, and to get everything done, I developed a system whereby I first diagrammed my plan on a single sheet of paper using circles and arrows, then wrote a series of outlines, the last of which had at least one sentence per paragraph of the final paper. I'd then take that outline, sit at the computer, and type up the paper pretty much in one take. 4. Troff. I wrote my senior thesis on a campus computer which printed out really nice--not that yucky dot-matrix stuff. I formatted it using Troff. 5. Pencil and paper again. For homework assignments in graduate school I went back to pencil and paper. I was still doing graphs by hand on graph paper (but that's another story). 6. Latex. One of my colleagues told me about Latex, and this quickly became my standard. When I wanted to write an article, I'd take an old latex file and map out sections and subsections, then fill in different parts when I was ready. I did it this way for several books and a few zillion articles. I have to admit, I've never learned Bibtex, so I spend lots of time cutting and pasting bibliographic references. 7. Html. A few years ago I started this blog (originally intended as a way for members of our research group to communicate with each other). I often use the blog to record thoughts that later are published more formally. Writing in Html puts these thoughts in a different shape than what was happening in Latex. More conversational, less locked into a formal structure. 8. Word. Recently, for some reason I've been writing articles (and our forthcoming book) in Word, which doesn't work so well when I have formulas but somehow seems smoother otherwise. The medium does affect the message. In many ways I'm dissatisfied with my current approach of composing at the keyboard. Maybe I'll try pencil and paper outlining for awhile. Oh, yeah, . . . happy new year. June 18 Mozilla正式发布Firefox 3CNET科技资讯网6月18日国际报道 Mozilla基金会周二开始提供Firefox 3的下载,这一开源项目正在开辟浏览器战争新阵地。 随着浏览器由静止知识仓库变成字处理器与图像编辑器等程序应用的基础,它的功能也从单纯的信息过道变成程序运行工具。在这个新时代,Firefox逐渐成为上个时代网络优胜者,IE浏览器的竞争对手。 Mozilla平台工程部的主任Damon Sicore说:“随着程序越来越大,越来越复杂,浏览器的速度变得越来越重要。” Firefox 3在Gmail中从一封信转到另一封信的显示时间为60毫秒,IE7为413毫秒,Firefox 2为227毫秒。 微软正在开发IE8,已经发布了IE8测试版,第二个测试版也将于8月推出。微软IE部门总经理Dean Hachamovitch,他们对IE8进行了重新设计与性能上的改进。他说:“IE是大部分用户的选择。它有质量的保证,易用,可靠,安全性也很好。” Mozilla是一股不可忽视的力量,Net Applications statistics数据显示,Firefox市场份额为18%,IE浏览器为74%。这一份额足以让主要的网站要考虑支持Firefox。 苹果Safari浏览器现在也推出了Windows平台版本,市场份额为6%。其次是Opera,不到1%。 微软清楚浏览器市场存在大量竞争。Hachamovitch说:“现在有大量浏览器产生。过去几年,很多创新出现。” Firefox积极的进行竞争。为了提高形象,Mozilla希望创造Firefox 3一个24小时的下载纪录,开始时间为美国太平洋时间上午10点。 Firefox 3的速度更快,内存占用更好,此外,Awesome Bar自动网址查找功能也令人眼前一亮。 为了测试内存占用情况,Firefox 程序员打开了500个页面,然后关闭,打开这些网页上千次。 Awesome Bar官方称谓叫做Smart Location Bar,它让用户可以输入单词来替代网址输入。例如,输入“地图”一词,Firefox 3可以列出最近访问过的地图网站清单。 Firefox 3其它功能包括: ·当用户试图打开一个含有恶意软件网站时,Firefox 3会发布显著警告。 ·离线数据访问功能。 ·Cairo图像引擎让浏览器与电脑的显示硬件更融合。 ·支持动画PNG图片格式。 ·更好的全页面缩放功能, ·支持Windows Vista的家长控制功能。 ·更好的支持Mac OS X操作系统。 Firefox的一大特色是支持丰富的插件。一些主要的插件已经支持Firefox 3,包括雅虎的Delicious以及面向网站开发人员的Firebug工具。 Firefox 3官方下载地址:http://www.getfirefox.com/ |
