title: vim on virtualbox startup is slow when connected via putty
body: <p>I am running freebsd on virtualbox (with virtualbox-ose-additions installed in freebsd).<br />
  the vim startup is very quick (instantaneous) in the vbox console window.<br />
  but when connected via putty from the host machine, the vim takes about 6-7 seconds to startup.<br />
  the connection from putty is via ssh authentication.
  and the host to vbox connection is NAT+portforwarding.</p>
