Ravi,
spoke to a guy that does performance testing/improvement for Oracle
Applications. He said that there is some % CPU in Trindad but I would
not give it more them 20%. The heavy hitters is getClientId (Blake -
see dev@ thread - is doing some optimization there).
Now if getProperty is some el
Matthias,
If the issue is in bean, it should show up in my analysis. Also
getProperty is only 40% CPU, there is additional 45% cpu consumed by
rest of the trinidad classes totaling 85% total CPU, all within
org.apache.myfaces.* classes

Another thing, most of our EL expressions are one of the following types

or
#{bean.get['memid']}
Parsing of these expressions probably happens within org.apache.myfaces.*

time. We know, the final getter
Maybe it happens when accessing the value from the Map with
#{bean.get['memid']}, because the Map is not properly synchronized, thus
its internal structure is broken and thus it is running in infinite loops.
Are your resources properly synchronized?
Just a guess in the blue...

I am thinking if that was the case, I would see high CPU in
java.util.HashMap instead of org.apache.faces.*
If you disagree, please explain and I can try using HashTable to store data
and get fresh numbers.

We have load tested our Trinidad application with up to 800,000 page
loads/hr. and the application handled it fine. We have also simulated up to
190 concurrent users. We are using MyFaces 1.1.5 and Trinidad 1.0.5. We are
using the Oracle Application Server 10GR3 and are running on Linux.
Hi Ravi,
Just a stupid question. Are your beans extremely big? Since FacesBean
doesn't do much locking/synchronizing (none if I'm correctly), the
only reason I can imagine it to eat CPU cycles is because of its
size...
Also, is it possible for you to do a profiling run using VisualVM?

Jakob,
The beans are not big. Also these tests have been performed under a single
user to measure the CPU timing. So I doubt locking/synchronization is an
issue.
I would think that if there is synchronization, then the threads could be
waiting for long time, but lack of synchronization can only

If you are running on Windows, what does the TaskManager show as the CPU
utilization? How much memory is also being used? 2Gb is not much memory for
a production application. I have that much on my desktop.

The memory 2GB is not much for a server but even that much is not being used

The numbers I posted are from my desktop (which has 4GB memory) as it is
easier to profile CPU on local desktop. The CPU usage is fairly

Jakob,
I did install VisualVM but it is not capturing org.apache.* classes or
com.mycompany.* classes. I did not find a setting on how to enable capturing
data for all the classes I want. Can you tell me where to specity the
packages for which I want to capture CPU usage?

Hi Madhav,
JSF always submits back to the original view, if you hit a h:commandButton
or h:commandLink. So if you are on index.jsp and hit for example a
h:commandLink, you will get a request for index.jsp. However, after the
action method on the server is finished, the server renders the new

To your question: Can you explain little bit how lack of synchronization can
add to CPU?
I don't know exactly, but maybe it is possible that the internal structure
of a Map (e.g. HashMap) can be destroyed when there are multiple change
operations (put, remove, clear) at the same time,
Oh I see what you are saying. We only create and populate the hashmap once,
we never clear or delete from it. So that endless loop is not the problem.
Also in that case the CPU wouldnt show up for org.apache.* classes.
I guess you are looking for how to specify packages in VisualVM. This would

So basically your system can handle 18.5 pages/CPU/second. I can only

If you can get that kind of performance, I wonder what is wrong with our

What you have mentioned is already known to me. That is the reason I have put a

I should have made it a little more clear. Apologies for that. The forward from
index.jsp to login.jsp is via jsp:forward.
Hi,
which mapping do you use for your faces servlet: postfix (like *.jsf) or
prefix (like /faces/*)? Maybe the real JSF urls are not listed in your
intercepter config.
