I just downloaded build 361 for runtime and addons. I uncompressed both, copied items and sitemap from alpha2 release and started OH2.
I have only 3 zwaves devices on my installation (controller and 2 switchers) and when I switched one device I got a 30 seconds response time. As this was working fine with alpha2 release, I removed all unneeded addons. I only have now zwave, yahoo and hadmin jars files. And now, my response time is fine. It is almost instantaneily.
Any reason for such behaviour?
