JSF Performance Problems
I grabbed the attachments from the original performance bug
https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=3 and ran some
JMeter tests against the "JSP only" and the JSF versions.
The pages are really simple, the JSP version outputs a page which is
visually identical to the JSF page. The table in question had 10 columns and
50 - 200 rows. Not a huge amount of data. I used MyFaces 1.1.3 as the JSF
implementation and ran the test in JBoss 4.0.4 GA running on JDK 1.4.2.
Here's the results:
Table Rows Average [ms] Median [ms] Hits / Min Samples
JSF Testcase 50 36 30 1300 5007
JSP Testcase 50 14 10 4030 5001
JSF Testcase 100 56 60 1050 5001
JSP Testcase 100 21 20 2700 5001
JSF Testcase 200 100 100 590 5001
JSP Testcase 200 26 30 2170 5001
This data confirms the discussion in the sun forum. The JSF version started
out nearly three times slower than the JSP page. The relative performance of
the JSF version degraded to nearly four times slower as table rows were
added.
So if you are thinking about adopting JSF you should be aware of the
performance hit and make sure that you can architect around the problem or
get the performance benchmarks adjusted. Perceived performance is important
in real life projects so it's more than a theoretical problem.
I'd also like to know if anybody has ideas or code samples that make JSF
perform better?

Your right - if the project will involve showing a 200 row table to users ten times a second. Any medium to small sized website should first consider JSF's ability to reduce bugs and development time, rather than worry about pages showing 50ms slower. If users are hitting your website fast, count on your backend portion (i.e. SQL queries) being the area that needs to be addressed first.

Could you please rerun the metrics with the performance tuning suggestion found at:
http://wiki.apache.org/myfaces/Performance
Thx.

Is the result with Myfaces/JSP? Can somebody provide performance comparison
with Myfaces/Facelets?
JSF is still a new technology, and there are still plenty of rooms for
improvements. Furthermore the performance differential won't be as drastic
once we factor in business logic, persistence, AJAX etc.
IMHO reduce development time is still the most important factor to consider.
