[Building Sakai] extremely slow loading for home tool of the site

[Sanghyun Jeon]

Is there anybody who fixed this issue?
We don't have this issue on our test instance, which have the same java and
tomcat binary codes. This happens only on the production instance.
When user clicks the site with the home page for the first time, there is
no log on access_log, and after a while, GET
/direct/session/current.json?auto=true&_=1407930848211 HTTP/1.1" 200 273 is
shown and then  "GET /portal/timeout?auto=true HTTP/1.1" 200 202
 and then "GET /portal/site/user_requested_siteID HTTP/1.1" 200 22994



When user clicks the same site for the second time, the log says  "GET
/portal/presence/user_requeted_siteID?output_fragment=yes&auto=true&_=1407933607235
HTTP/1.1" 200 251

Looks like portal time out is called for the user's first time visit and
don't know why and I am wondering there is some experts who can tell what
is wrong with this procedure. User needs to wait to loading the home page
at least one minute or so. Thank you in advance.
