We recommended the following as general guidelines:
|Number of Concurrent Sessions||Recommended number of IPSec VPN Tunnels||Recommended Total Bandwidth|
Bandwidth requirements for testing depend on the number of pages downloaded by each test, and the approximate size of each page. To estimate your requirements, we recommend running 25-40 concurrent sessions through a proxy while observing network usage patterns. You should have enough bandwidth to download a page in 3 to 5 seconds.
