Julien Viet commented on GTNPORTAL-506:
---------------------------------------

I have added more caching for portal navigations, it should resolve this problem. Reopen this jira if you still see a degradation.

> There is small performance degradation for each visible page on navigation portlet (navigation bar). Since method getPage from UserPortalConfigService is called for each visible page on navigation bar and it costs some time even if pages are cached. so rendering of UINavigationPortlet costs more time.
> Degradation is not big. When the request is sent to page on portal with only 2 visible pages on navigation bar, then maximum throughput was 527.8 requests/s. If there are 6 visible pages on navigation bar, then maximum throghput is 491.9 requests/s. So small difference but it's here.
> Performance degradation is not here, when pages are configured to be non-visible in portal.
