After installing several svn versions I found out that for versions until r7459 the time for loading project files is amazingly fast, but from version r4760 on there is a huge delay in loading them. What did change in codeblocks and how can I disable this feature?
Did you mean: r7460?
But I can't find any reason why r7460 will be slow than 7459.
What's changed in r7460 looks like:

I can confirm that loading large projects is very slow.
Not here, but it might depend onthe place where your project file is located.
The ProjectDirTraverser is only called from inside CalculateTopLevelPath, and that should not happen so often.
Can you apply the following patch and start C::B with "-d" parameter, and have alook ath the "Code::Blocks Debug".
You should see how often the traverser is called and how long it needed.
You can also try what happens if the CodeCompletion-plugin is disabled.
