I really think not a single environment can be compared to another one. I have three production hubs
- Coordinator - C4 - no stick inserted
- ZWave Hub - C4 - USB stick radio with Zigbee disabled
- Zigbee Hub - C5 - Internal radios, Zwave disabled
For the sake of it, I am only going to compare my ZWave and Zigbee hubs as these only have 1 custom app installed (Hub Watchdog)
As you can see, the Zwave Hub (C4 HW) is significantly "faster". Now, this can have several reasons:
- I use a lot of Iris V1 contact sensors on my Zigbee hub that are known to be chatty
- There is a difference between C4 and C5, while it was made clear by the team there shouldn't
- Something else that we are all hinting for
Do I see slowdowns on these two hubs? Yes, but only on the Zigbee C5 hub. The Zwave C4 hub has always been rock solid. I just installed HubWatchdog on my Dev hub which is also a C5, I removed all custom apps and this hub does not have a single real device attached. Early indication is that the times for this hub is in between the two other production hubs but time will tell and I will report back.
What that could also mean is that the performance of the hub is very much on which real devices you have attached to your hub, that is why I say that you can't compare one user to another.
There is one thing I would be very very curious about but we can't get to that data. The platform relies on an underlying database. I would love to see some statistics in regard to database read/write performance to see if there is a trend over time. Reason is simple, a lot users that have a problem report that a soft reset with restore makes the hub feel "faster" again which could point to something in that area.
