Hm, IMHO you may consider redirecting parts of the roaming profile if=20
you have
that size of the profile. Also, be sure you tweak the size of the local=20
cache, we tested
with 300MB in profiles (16000 files) and it was really slow if we did=20
not increase the
cache sizes to be larger than that.  After that the login times were=20
