Subject JSF application very slow with HTTPS
Date Mon, 11 Apr 2011 11:49:04 GMT
  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

Regards,
Michael
