Deleting files to improve checkout time

We have a version of our project that we tagged created with rtag -- and it has a large number of files which causes checkout to be exceptionally slow.

A lot of the files are obsolete, so I have deleted them and committed this change to the repos开发者_如何学运维itory. However, the checkout time has not improved because the files still exist on the server and are subject to processing when a new checkout of this tag is made (but they are not checked out).

Is there some way I can either disable this processing, or permanently delete the files, but not affect any other tags or branches?
