Hi,
I've ran into performance issues when running a MyFaces + RichFaces apps on Tomcat. When rendering JSF components, myfaces ends up calling Request.getAttributeNames() repetively. I profiled an application while rendering a single relatively simple page and found 1000+ calls to the function. Calling getAttributeNames() in Tomcat 6 is a relatively slow operation when there is an SSL connector configured in the server. Thus the massive amount of calls to this function ends up taking a substantial amount of time in respect to all processing required for executing the request. I filed this in the JIRA. The bug report contains version numbers and a short trace from the profiler session. https://issues.apache.org/jira/browse/MYFACES-2823 Sampo
