Is nscd running?  You don't mention how you are authenticating, but I
have found that if I don't have nscd running on our systems (both the
ltsp server as well as the authentication server), then logins can be
exceptionally slow.  We have 1300+ accounts active at present and no
issues with logins but we are also still using LTSP 4.2.  I also
noticed during my testing of K12Linux that logins were very slow but
thought that was due to a bug (have to search the LTSP forum) which
was fixed in a later patch.
