Possible bottlenecks are described below.</p><p><h2>Content retrieval<br/></h2>The performance of the content retrieval depends mainly on the actual persistance manager. Depending on the filesystem this is not necessarily an issue (for example one can use memory based filesystems for high performance environments), whereas in the case of databases one normally uses session pooling (also see <a href="scalability.html">Scalability</a>) and sophisticated caching mechanism of the database solution itself.<br/><h2>C!
ontent generation</h2>The performance of the content generation depends very much on how custom resources are aggregating/generating a response. Yanel doesn't set any restrictions on how this is being done and it mainly depends on the technology a custom resource is using (for example XSLT, Jelly, POJO).<h2>Access controlling</h2>Each request (URL) is being checked for authorization, but Yanel also allows <a href="../security/overview.html">content based access control</a> which can lead to many more authorization checks depending on the setup. Fortunately Yanel allows to use custom implementations of the access control policy manager per realm and hence one has always the mean to improve performance re access control.</p></body>

The important thing is that Yanel allows one to choose any kind of persistance manager either by accessing it directly from within a resource or by using one or the other content repository API (for example JCR or Yarep).</p><p>The implementation of the content navigation is also <a href="../realm/realm-configuration.html#repo-navigation">configurable</a> per realm and hence does not lead into any restrictions.</p><h2>Session wise</h2>The scalability of the number of concurrent sessions is of course !
related to <a href="performance.html">performance</a> in general, but since Yanel is clusterable it also depends on the right choice of application server. There are many well-known Java based application servers, for example Tomcat, Jetty, JBoss, WebSphere or WebLogic. Since Yanel itself nicely separates the application from the data handling/storage, one can easily deploy Yanel on multiple "working" machines (second layer) behind a load-balancer (first layer), whereas the data storage could be on separate shared machines (third layer), which are for example mounted by the "working" machines and replicated by the persistance manager itself, whereas the repository journal would be shared by the working machines.</body>
