Yep, that's what I'll do after getting the app running on jetty.
What a pain, I thought this would have been done in a few minutes ....

Ah sorry, have overread that:
The time is spent in
htmlTableRenderer.encodeInnerHtml
I'd start the application with YourKit profiler and do some profiling.
You can get a free yourkit test license (14 days I think) for evaluation.

Fat? Well there is a lot of EL
in this table, nearly in all cells,
e.g. for column widths, values, styles etc.
The EL is always hitting backing beans, some with
additional map access.
But the real problem is the poor HTTPS performance compared
to HTTP.
It should not be caused by the app and also not by JSF or
Tomcat of course.
There should be a little overhead for additional
handshaking, but not
for the rendering!
Could this be caused by a buffering whereever?
Mark (or anybody else), did you compare your app with http
and https?
Just wondering whether this is a problem only in my app.

Michael

Btw another question: 1s local response time? How fat
is this page?
We have a really big page in production with 1400
lines in a dataTable - and it renders in 450 ms...
How many back-and-forth requests do you see if you
open firebug?
Do you have some EL involved which isn't hitting the
backing bean but directly goes into the database? Something
in this direction...

I also use
jetty-6.1.22. My environment is
almost
identical to
yours, give or take a minor version number.

Hi,
My JSF application is very slow via HTTPS.
Some parts are 15 times slower compared to
HTTP
I measured the response times of the xhtml
requests
with Fiddler (locally
and over network)
Result for a very large page (512 KB) with a
big
datatable without ajax
usage:
-- local access with HTTP: 1 sec
-- local access with HTTPS: 15-16 sec
Other pages are factor 2-4 slower, with or
without
ajax.
The time is spent in
htmlTableRenderer.encodeInnerHtml. Data is of
course
available, there is no additional backend
access.
The simple download of xhtml files or other
files is
NOT (noticeable)
slower.
Other non JSF applications running on the same
servers
are also not slower
with HTTPS.
Before I start profiling:
- Does anybody have an idea where I should
look at?
- Are there any known JSF or webApp settings
that
influence https
performance?
Environment:
Facelets
myFaces 1.2.9
tomahawk12_1.1.10
richfaces 3.3.3
tomcat 6.0.29
jdk 1.6.0_23

Michael
