Well I have obtained a C4. It is up and running and the results of what I was trying to do are kind of interesting. Below is a screen shot of hub performance stats.
What is interesting is the way the CPU increased fairly rapidly after adding Lan based devices. At this point the only activities running on this hub are below
- Chromecast Integration,
- Chromecast Helper
- 3 servers with Ping drivers every polling every 5 min
- Roku Connect and 3 Roku devices with the polling processes running 5 min/10 sec/3 sec /240 min
- Ecobee suite with a few helpers running.
I also have Hub Mesh enabled to push device status's for certain zwave devices from the C-7 to the C-4 needed for some of the automations using those devices.
This is actually better then what I had initially deployed as my first attempt at this integration actually brought the C-4 to it's knees. I think i tried to include all my devices going both ways between the hubs with hub mesh and was a bit more agressive using the ping driver pools
My point here though is that this really highlights the power of the C-7 and probably the C-5. In those graphs above my C7 still has everything configured including what the C-4 is doing and really isn't breaking much of a sweet. Now if i push the polling faster on the devices i am sure the C-7 will show impact, but as of now it isn't flinching much at the same load.
I know a previous poster made a comment about the 64bit JVM being a performance hit, and i don't think it should be this pronounced. I almost wonder if there is a issue with the Network PHY device or driver that is impacting this. Either way for me this really does put a damper of using the C4 for pretty much anything other then minimal dev work at this point. Oh Well. I think i can use the Zigbee/Zwave stick with HA if i want do dabble there
And yes I know i should have expected to much with something 2 gens back
