Whatever's wrong with your VPN doesn't seem to be easily reproducible.

Do you know if there was any recent upgrade to the VPN gateway(s)? If
there's an alternate/backup gateway then it may be worth trying that
gateway to see if it's more any reliable, or pestering your IT
department about the problem.

Unless the problems with your VPN are due to a lossy or extremely slow
connection between your computer and the gateway… then it probably
won't be significantly slower.
