Just migrated from HS3 to HS4 and wish I hadn't.

You can disable the Z-Wave (or any other) plugin to see if it makes a difference.

Ahhhh! I found it ... it's not the Z-Wave plug-in, it's HSBuddy! Once I disabled that my events page went back to loading in about 2 seconds. Off to ask about this elsewhere.

Just found out about using _events.html and it works so much faster, so I'll be using the old HS3 interface when I need to make mass event changes.

Not for long! The legacy HS3 events page will be removed as it will not work with the new event conditions coming in 4.2.18...

That said, the 1gb Pi3 is going to be slow. I ran my system on a Pi4 4gb and it was quite good, not nearly as fast as my Windows machine and very slow loading the Event page. TBH, a dual core Pentium or Atom is slower than I would like on my system.

Hmmm…. I have 4768 Devices and 1650 Events. My event.html loads in 2 seconds.

Geez. I only have 10 plug-ins, 362 devices and 132 events but this is on a HomeTroller Pi (RasPi 3 B, 1gb RAM, 32gb micro SD). I've read it could be related to the Z-Wave GUI plug-in (4.1.0.3 BETA) and I do have a lot of Z-Wave devices.

The new beta has a change labeled as:



Now, I dont know all the details of the case, but it might be a way to speed up processing under the hood of HS...

Per my post Energy Management Plugins above, I can tell you the calls to plugins is quite excessive when the events page is loaded.

This is still my only major as problem as well ... the slow events page really makes editing/changing events painful. I've started using the back button in my browser to go back to the events list after making changes to an event to avoid that "refresh tax."

Every time I hit events.html it takes 30 seconds to load, this includes trying to activate/deactivate events. Is there any chance this will be addressed?

I have a performance problem OPENING the events page.

That slow event loading page is REALLY the only HS4 issue I have. And it is relatively new.

I am on 4.1.0.3... If it is working, don't change.

I’ve tried every V4 plug-in but had to immediately roll back due to problems. Each successive version has been better, but still breaks important things in my system.

What version of the HS4 plug in are you using? I saw this pretty recently.....

I don't see the CPU move much at all when I go to open it. I am on a ESXi VM on a 4-core XEONs. If I have events which are red (ie. reference deleted or no device_, it is much worse.

Z-Wave 3.0.11.0

I know this is practically useless info, but I am not seeing these issues with:

Device Count 4727
Event Count 1656
Z-Wave Devices 188
Plug-ins 30

Event page (either HS4 or legacy) takes 2-3 seconds to open. Xeon 6-core low power processor at 3.7ghz.

rmasonjr stated this may be related to the number of plugins, not devices or events.

Could it be a plugin that is very busy and therefore taking a long time to respond to HS requests for information?

I'm on device 830+ so that may be the reason. Sounds like a poor design decision that worked on the small test case but does not scale up.[Not that I have not done that on other projects]
