1. The test was conducted with 50 tags on the master pc. 2. It takes an average of 2 minutes and 20 seconds to switch from master pc to backup pc. 3. Please let me know if there is a way to speed up the transition time. ---

That is astonishingly slow. I have customers with redundant systems with tens of thousands of tags that transition in single digit seconds (after the configurable detection time--typically ten seconds). Oh, wait, you tagged this for Perspective. /: ---

Yes, we're testing with perspective right now. ---

Is it fast if I do it with vision instead of perspective? ---

This might be something better handled via support. Either way, you aren't explaining how you're inducing failure/failover and what it is you're actually measuring in terms of how long it takes. ---

Yes, what I described above was Vision. ---

I haven't used Perspective with redundancy. Sorry. Someone else will have to chime in. ---

He (Phil) means that he hasn't used Perspective / Perspirationâ„¢ with redundancy so he doesn't know. But you haven't answered Kevin's questions > [@Kevin.Herron](#): > > Either way, you aren't explaining how you're inducing failure/failover and what it is you're actually measuring in terms of how long it takes.
