些使用java的大型站点。
indeed.com
工作搜索引擎，在德州。以lucene, java为主
become.com
大型的比较购物搜索站点。由韩国人建立。他们的crawler介绍如下文章:

nextag.com
大型的比较购物搜索站点。在shopping comparison engine方面是主要的player
shopzilla.com
大型比较购物搜索站点。在加州LA
LinkedIn.com
大型的工作社交站点。
amazon.com
他们的平台逐步从c/c++/perl向java移植
expedia.com
大型网上订购机票站点。他们的supply chain系统正在从c/c++向java移植
可见，java已经进入了high performance server端，不再是c/c++的天下了。。。
连google现在也在用java |

发帖数: 692 | 8 php/perl code is not maintainable and scalable. Recently, I am working on
some php stuff. It is really a bad experience.
php is good at hosting, low memory usage. However, for those sites, they
have enough resources to purchase high performance machine. For example,
Linkedin, they load entire user graph into the memory that only occupies 2/3
G memory.

效率是高。但，程序不好维护。不好维护的程序，就无法迅速满足business/market的
要求。比如说，做新的feature等。所以，Java有优势。

Go to shopzilla and search for jobs. They got quite some java job openings
available. Don't know if they have fully migrated to java, but seems java is
the way to go for them. I even got some calls from recruiters for their
jobs.
BTW, their current website sucks. When you list your products there, you
couldn't even search for your own products.

In fact, indeed.com is a job search engine and it has huge amount of job

So, java is scalable and I find it really good to work with.

发帖数: 3271 | 23 Serve side Java Performance 没有任何问题
Serve side JVM经过优化跟速度比C#快等同于C++
JAVA主要慢在两个地方, 一是EJB, 但这不是JAVA的毛病,
所有采用这种封装的技术都面临类似问题, 不管用不用JAVA
二是数组和循环操作, 这是JAVA的语言定义死了的, 没有办法
所以JAVA用来做科学计算确实不行。但多数SERVER SIDE应用
不存在这种瓶颈。
所以JAVA的scalability一般来说没有什么值得担忧的。

I don't think that is still happening since jvms started
using generational GC. We have just finished our first round
of GC tuning last week on the project I'm working on. Our VMs
run full GC only occasionally. Most of the time GC runs
incrementally, with each round takes less 500ms, _without_
pausing most part of the VM.

件产品都是围绕Java的)的主要客户列一下，你就会发现相当高比例的F500都是或多或
少在用Java. BEA在被Oracle 收购前，每年光是在中国的用户大会就有上万人参加，
来得都是大型企事业单位，这些单位对Java没兴趣的话参加BEA的会议干啥？
从工业标准、安全性、分布式事务处理、对传统系统的接口等方面看，Java平台都有很
成熟的解决方案，再加上最大的中间件厂商的全力支持，大型网站用Java不奇怪，而且
