Not really possible to answer as it depends on who is looking at the packets and how much time and processing power they have.<br />
<br />
Anyway as a rule of thumb start low and baseline with a transfer across the wire. then start to ramp up the encryption and test again using your baseline method. <br />
Stop when you can't use the line to your users satifaction.<br />
<br />
<br />
You could augment the security in your model by using PGP encryption to protect you sensitive data: on files being transfered and Email etc.<br />
<br />
this is a good article (maybe old but still true)<br />

Which IPSec encrytion provides the best balance between speed and security?

IPSec Encrytion

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.
