Extremely slow HTTPS

Hello!

Thank you for SVNKit it is really a great library, although I've got some problems
regarding the https protocol. Of course I am using the latest SVNKit version and JDK.

The thing is that the whole thing works, and at the moment I'm only trying to print out a
repository tree according to the sample at https://wiki.svnkit.com/Printing_Out_A_Subversion_Repository_Tree

If I access the Subversion server through a web browser, it is very fast and nice, but through my Java
code it takes about 3,5 minutes to just fetch the 25-30 entries (directories) and print them.
The time is relative to the amount of entries. 7 entries take about 45 seconds. I have even removed the recursive
code so that the entries in the root is the only thing that is printed.
It is this line:
Collection entries = repository.getDir(path, -1, null, (Collection) null);
that takes the awful amount of time to get pass.
If I try to access http://svn.svnkit.com/repos/svnkit/trunk/doc and print the tree it is as fast as it should be.

Has anybody else had this problem? Unfortunately I'm doing a project for my school and I don't have
the configuration for the subversion server itself.
I will give you the entire code below if you need it, thank you very much for your replies!
