Possible performance regression in EPP 5.2.1 -------------------------------------------- Key: GTNPORTAL-2547 URL: https://issues.jboss.org/browse/GTNPORTAL-2547 Project: GateIn Portal Issue Type: Bug Security Level: Public(Everyone can see) Components: WebUI Affects Versions: 3.4.0.M01 Reporter: Vu Viet Phuong Assignee: Vu Viet Phuong In process migration redhat.com EPP 5.1.1 to EPP 5.2.1 and during test they notice that the initial page load time was very slow . After enabling logging the time seems to be spent in multi calls to the PageTask.Load For a single request to one page results in other pages of the same navigation level to be loaded for example if user request homepage via this uri http://localhost:8080/portal/home in epp 5.2.1 sitemap ,register and groupnavigation will be loaded too! Executed [ 29] PageTask.Load[ownerType=portal,ownerId=classicname,homepage] Executed [ 23] PageTask.Load[ownerType=portal,ownerId=classicname,sitemap] Executed [ 24] PageTask.Load[ownerType=portal,ownerId=classicname,groupnavigation] Executed [ 25] PageTask.Load[ownerType=portal,ownerId=classicname,portalnavigation] Executed [ 25] PageTask.Load[ownerType=portal,ownerId=classicname,register] So each page load time takes seconds with millions of records in the database and many navigation node In epp 5.1.1 only homepage is load What happened and why ? is there really a regression related the new navigation API ? We appreciate your quick response and help it's it blocks their migration to EPP-SP 5.2.1!
