RoR到底是个什么东东，能举个例子说说它和php的关系吗？是不是类似j2ee和java的关
系？为什么很多小startup都用这东西作de facto工具。 | s*******h

BSO一个小时写出个BLOG网站等等.当然也比PHP运行慢. | f*********y

drupal下面用得语言是php。

发帖数: 2172 | 7 Ruby is language
Rails is the framework
Overall:
J2EE is good for large and complex enterprise application
.Net is good for small to medium size enterprise application
PHP, ASP is good for websites that do not need a lot of backend integration
and interface with other site.
Ruby on Rails is good for beginner who want to learn and compose a site in
the shortest time.
.cgi is good for site need the best performance.
Cold Fusion is easier than PHP and ASP but not as good.
These are just a rough imp

发帖数: 2172 | 10 其实Servlet/JSP 是在性能最差之列, JSP 本质上就是Servlet, 根本原因是it要在JVM
上run. Application Server 的 Overhead 也很高, 如果再构架的不好, 用上一堆
third party .jar files, 那基本上慢得不能用, .NET 也一样, 要在CLR上RUN. CGI
如果用 C 之类的写, 可以直接编译成NATIVE CODE. 我以前看过一个BENCHMARK 说, 同
样的操作, 用CGI在一定的时间内可以RUN 300次, PHP/ASP可以100次, J2EE和.NET只能
30次, COLD FUSION比PHP/ASP稍微慢点. 当然和PHP/ASP之类的比, Servlet/JSP也不是
任何时候都慢, 比如大量数学计算, JAVA要比SCRIPT LANGUAGE快, 但还是远比不不上C
之类的可以编译成机器语言的语言.

发帖数: 9224 | 14 I am a java guy. I don't like those scripting languages for performance
critical situations. So, php, ruby on rail, those to me, are out of the
question.
To be frank, to me those are "kids" stuff.
If c/c++ could be run on all platforms, I would be happy to use a compiled
language like c/c++. Right now, the closest to me is java. | e******x

IT8097, I totally agree with you. I think java performance has improved a
LOT these couple of years. Also, it is a good trade off using Java. You gain
the easy development using Java, but also good performance in runtime.
I don't like struts or hibernate either. struts is too complicated.
hibernate is like another shell around database. So, from my past experience
, struts or hibernate won't deliver the good performance for the website.

发帖数: 2172 | 21 struts or hibernate, EJB, 甚至J2EE都不是用来做一般的网站的, struts or
hibernate用来做大型的ENTERPRISE APPLICATION的, 把多个层之间的结构理清的确比
较容易构架,容易分工.
用J2EE来做一般的网站注意点的话的确performance 还可以, 但万万比不过PHP之类的,
好象连.NET都比不过, .NET的JIT做得比JAVA性能好, J2EE来做一般的网站的最大问题
是开发周期太长, 用PHP之类一小时能干的事情, J2EE可能要两三小时或更长. STARTUP
可能损失不起这个时间. 当然JAVA 有很多好的PACKAGE, 比如Lucene, 要用这些的话
可能只好用J2EE.

Also, become.com, is written in java too.
