Redmine

It is not normal to wait 40! minutes for a checkout of 4mb. As you write this happens when you execute 'svn checkout ...' in a console, that is not in Redmine. It seems you have some problems with your connection between the svn client and the svn server.

I tried to remove the authentication and speed has increased dramatically. I've checked all passenger settings and everything seems correct. Not if the problem is in communication with redmine mysql or makes a kind check when authentication is enabled. No more do you test if someone can help me I would appreciate.

I suspect that you have a lot of files to checkout. svn will generate a request for each file and, in your environment, there will have a supplementary request for authentication in ldap so it may take a long time...
Did you try to use RedmineCacheCredsMax 50 in your apache configuration file (for the subversion access) to speed up the process? This is an option to use with redmine.pm which avoid to make the ldap authentication for all requests...

Thank you very much!!!, had the whole weekend stuck with that and did not know what else to look. I appreciate your help and confirm that that was my problem. I added the line RedmineCacheCredsMax 50 as you have recommended and works properly.

regards and thanks again.
