在开发环境中,不需要太考虑服务器的长期性能,并且内容将更加频繁地改变,因此高速缓存将成为障碍而不是帮助。
In a development environment, long-term performance of the server is not likely to be a priority, and content will change more frequently, thus the caches can become a hindrance rather than a help.

在动态高速缓存(通过WebSphereApplicationServer管理控制台)和Edge服务器(通过plugin-cfg.xml文件中的参数)上都可以配置分配的内存数量。
The amount of memory assigned can be configured for both dynamic cache (via the WebSphere Application Server admin console) and at the Edge server (via a parameter in the plugin-cfg.xml file).
如果您熟悉高速缓存,从本质上来说会话与它是相同的概念—存储数据以减少响应时间和服务器工作负载。
If you're familiar with caching, it is essentially the same concept — storing data to reduce both response time and server workload.
高速缓存使您的应用程序速度更快并且减少了服务器上的负载。
Caching makes your application faster and reduces the load on the server.
例如,如果您正在编写一个Web服务器,而且所有的高速缓存的页都存储在hashmap中,那么每个请求都将需要获得并占用那个map上的锁,这就将成为一个瓶颈。
For example, if you are writing a Web server, and all your cached pages are stored in a HashMap, every request will want to acquire and hold the lock on that map, and it will become a bottleneck.
对象高速缓存和合用:应用程序服务器自动在服务器级合用无状态会话bean,这减少了花在对象创建和垃圾收集上的时间。
Object caching and pooling: the application server automatically pools stateless session beans at the server level, reducing the amount of time spent in object creation and garbage collection.
高速缓存代理提供了一个高速缓存解决方案,但是通常位于Web服务器的前面(距终端用户更近)。
The caching proxy provides a caching solution, but is typically placed in front of the Web servers (and closer to the end users).
动态高速缓存(也称为WebSphere动态高速缓存服务)是应用服务器上默认启用的WebSphere服务。
Dynamic cache (also known as WebSphere dynamic cache service) is a WebSphere service that is enabled on an application server by default.
数据库服务器可用的高速缓存内存数量可能是影响性能的关键因素。
The amount of cache memory available to the database server can be a key factor in affecting performance.
客户浏览器然后将对一个URL的请求直接发送给高速缓存服务器以检索一个文档。
The client browser then sends a request for a URL directly to the cache server to retrieve a document.
除非是在特殊的环境中,否则用户永远不会意识到客户机和服务器之间有一个高速缓存。
The user may never realize that the cache is between the client and server except in special circumstances.
透明的代理高速缓存也使全部流量转向高速缓存服务器。
Transparent proxy caching also diverts all traffic to the cache server.
ICP也不包含真正的安全性来保护高速缓存服务器间的通信。
ICP also contains no real security to protect the communications between the cache servers.
另一方面,如果设置拥有十台以上服务器的一个大型多层高速缓存,则ICP高速缓存将耗费过多的时间传播更改,这样就会降低性能。
On the other hand, if you're setting up a large multilevel cache with more than ten servers, ICP caches will spend too much of their time propagating changes and thus reduce efficiency.
通常,高速缓存服务器不需要系统管理员的任何干预,所以最佳的选择是相当稳定、可无人值守运行的可靠平台。
Typically, the cache server does not need any intervention from a sysadmin, so the best choice is a fairly stable, reliable platform that can run unattended.
在多个服务器之间协调高速缓存的内容是一个挑战。
Coordinating the contents of a cache among multiple servers is a challenge.
高速缓存服务器管理员都承认内存和磁盘存储是最重要的性能因素。
Cache server administrators recognize that RAM and disk storage are the most important performance factors.
它随后向其他高速缓存服务器发送一条CARP消息,其中包含要处理的原始HTTP请求。
It then sends a CARP message to the other cache server containing the original HTTP request to fulfill.
处理大量请求的更好的方法是使几台高速缓存服务器并行运行,以处理来自相同客户机或不同组客户机的各种请求。
A better way to handle high-volume requests is to keep several cache servers running in parallel, handling requests from the same clients or different groups of clients.
高速缓存服务器直接位于客户机和远程网站之间的数据路径上,并中途截取所有外发请求。
A cache server sits directly on the data path between the clients and the remote Web sites and intercepts all outgoing requests.
有了这些高速缓存协议,高速缓存服务器就可以同时查询所有其他服务器,以查看它们是否包含所需的数据。
With such cache protocols, a cache server can query all the other servers at the same time to find out if they contain the needed data.
这些并行高速缓存服务器通常包含完全相同的数据,并彼此沟通更改。
These parallel cache servers usually contain identical data and communicate changes among themselves.
只要在系统中添加第二个高速缓存服务器,就会遇到以下问题:如果多个服务器应该包含相同的数据,如何维护多个服务器之间的一致性呢?
As soon as you add a second cache server to the system, you encounter this problem: how do you maintain the consistency among the multiple servers that should contain identical data?
