Hi Chris: 1. I am instrumenting inside the servlet code, looking at Apache web server logs then at the Rich Internet Application (RIA)
For a typcial request for my Portal from client to servlet for example: 1. 4.55msec inside the RIA java code after the data was read from the SOAP message. 2. 0 microseconds read in the Apache Web Server logs 3. Under a microsecond in the servlet code for the service method. I have a multi-tier caching system so most of the request/responses are under 1500 bytes or the size of a single packet. Even if there is a cache miss most of the requests are still under 1500 bytes after compression by JAXWS web service code. Hope that helps.
