I'm experiencing major loading times on every page on my site, and after putting ?debug=true in the url I see that the events 'After DwNavigation(navbar)' and 'After: BeforeSort' takes about 21 seconds to load. 'After: BeforeSort' is used on pages with products on them, and when the gets the issue the 'After DwNavigation(navbar)' event seems fine, so the issue is only once per load. I have not gone through the entire web to be fair so some other events may also get this error.
Any ideas what might be the cause? It doesn't really tell me anything, and from what I remember I've had these performance issues for a while now so it's nothing new.
I realise that this isnt too much to go on, but at least some pointer on in which direction to start would be greatly appreciated.
