I loaded 126.96.36.199 yesterday. And other than during the Hubitat evening maintenance and backup, there has not been a single slowdown. I monitor it every 10 minutes on two devices using Hub Watchdog. This is the first time since owning Hubitat that I have seen a day like this, even with automatically rebooting daily at 4AM. Now I am not rebooting but instead just restarting the Hubitat process after 10 consecutive minutes of slowdown, and still had slowdowns. The Maintenance period always shows a slowdown for 3-6 minutes, and that may be understandable, but I have not seen a slowdown other than that since I loaded 188.8.131.52 yesterday morning. One day of no slowdowns may be premature to say it is totally corrected, but I am excited about the possibility. I will continue to monitor and let you all know.
For those that may know the details of what is in the latest release, is it possible that something done may have addressed one or more issues that might have been leading to this?
