Hi there,
For those interested in testing their hardware without completely setting up a securenode and connecting to the securenode tracking servers and consuming 0.0002 zen, you can run the following command:

zen-cli zcbenchmark createjoinsplit 1

This will then give you an output like

[
{
"runningtime": 88.07598
}
]

This is what your node will be able to complete the challenges in.
