There is a max amount of tunnels that an organization can start at any given moment.
The number you will receive is dependent on the org's concurrency (CCY) limit up to a point.
The way this is determined is:
- Every org has at least 5 tunnels
- If the org's CCY is anything in between 5 and 30 it will give you whatever the CCY is.
(Example: 15 CCY will get 15 tunnels)
- After 30 CCY the tunnel limit will stay at 30.
If set up correctly, a single tunnel should handle the load of around 100 concurrent tests.
The exact number, however, can depend on things like bandwidth, size of assets, among other things.
