I have a site that has long load times from a cold start and even after that response times are delayed for an unacceptably long period of time. This is a load balanced site across two servers and the install hosts 7/8 sites for different countries, it has quite a lot of nodes.

I have enabled the miniprofiler and continuously find at the start of the stack that the longest running item is similar to the following:

[PublishedContentRequestEngine] FindPublishedContent: Begin finders — 14776.90 ms

In the ApplicationStarting event I have the following which may or may not be related:

// Locates shared content in non-english sites
ContentFinderResolver.Current.InsertTypeBefore<ContentFinderByNotFoundHandlers, OrganisationContentFinder>();
ContentFinderResolver.Current.InsertTypeBefore<ContentFinderByNotFoundHandlers, OrganisationFolderContentFinder>();

// Replacement for v4/6 DateFolder structures
ContentFinderResolver.Current.InsertType<DateFolderContentFinder>();

ContentLastChanceFinderResolver.Current.SetFinder(new MultiSite404LastChanceFinder());

Can anyone shed any light on why this might be causing such a significant delay? It's something I would have perhaps only expected to see at application start up but it happens for every page request.

Umbraco 7.4.3
