I doubt that Raymond/Patrick will be successful in speeding up
ClearCase builds. I've had extensive experience with Samba and

Are you serving VOBs or VIEWs via Samba? VOBs shouldn't be an issue
although LDAP authentication might be a problem. We usually pass the
authentication to the domain controller (security = DOMAIN)

If you are serving dynamic VIEWs, forget it. Builds will always be
extremely slow. I've seen this problem with SAMBA and NAS using
CIFS. You are better off using local storage or accepting the slowness.
