On my machine the first request to get the list of patches takes about 5.6seconds: Processing PatchesController#index to xml (for 127.0.0.1 at 2009-11-04 14:18:44) [GET] Parameters: {"format"=>"xml", "action"=>"index", "controller"=>"patches"} Account Load (0.5ms) SELECT * FROM "accounts" WHERE ("accounts"."remember_token" = '32faf20594c95f7d7735261ac8d9f8cb7fa43803') LIMIT 1 Cache read: patches:timestamp #### Patch cache expired Expired fragment: views/localhost:8080/patches.xml (0.1ms) Cache write: patches:timestamp Cached fragment hit: views/localhost:8080/patches.xml (0.1ms) Cached fragment miss: views/localhost:8080/patches.xml (0.1ms) Completed in 5636ms (View: 5, DB: 0) | 200 OK [http://localhost/patches.xml] The next request (just reloading the page) is way faster, about 0.03s: Processing PatchesController#index to xml (for 127.0.0.1 at 2009-11-04 14:19:19) [GET] Parameters: {"format"=>"xml", "action"=>"index", "controller"=>"patches"} Account Load (0.5ms) SELECT * FROM "accounts" WHERE ("accounts"."remember_token" = '32faf20594c95f7d7735261ac8d9f8cb7fa43803') LIMIT 1 Cache read: patches:timestamp Cached fragment hit: views/localhost:8080/patches.xml (0.0ms) Filter chain halted as [#<ActionController::Filters::AroundFilter:0x7f7aaef82480 @identifier=nil, @kind=:filter, @options={:if=>nil, :only=>#<Set: {"index"}>, :unless=>nil}, @method=#<Proc:0x00007f7ab02f9e28@/usr/lib64/ruby/gems/1.8/gems/actionpack-2.3.4/lib/action_controller/caching/actions.rb:64>>] did_not_yield.

That fix doesn't make any improvement on loading "update" and "status". Even more, It is much slower to load modules than before. Seems it wait "Loading patch information" and "Working Loading system information". I think it is not necessary to show them on main page, because they can be shown in "Updates" and "Status" page already. Why not just delete "system is up to date" and "system is healthy." check on the main page? Reopen this bug because the slowness makes the customer feeling bad. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem is that both actions are very time consuming (that's why they are loaded via AJAX requests when the page is loaded). The patches module contains caching so the available patches are not evaluated/searched in every page reload, but the status module doesn't have any caching yet. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I cant reproduce excessive slowness running WebYaST + IE8 in VirtualBox
In order to compare, I tested WebYaST + FF3.5 in VirtualBox IE 8 and IE7 perform well on this issue. (take 1-3 seconds), while Firefox 3.5 performs bad (takes 3-10 seconds). Hope to fix this issue on Firefox 3.5 on later build -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
