After last night's configuration changes, performance improved again, and appears to be at a good level most of the time.
Performance started slowing down just before 6am Pacific today, and our automated monitoring restarted the system at 6:53am when response time exceeded 20 seconds. We don't want to reduce the response time threshold for restart further, otherwise we are likely to cause unnecessary restarts.
As I write this, the VMware Communities team and community members continue to report good performance (except for the slowdown noted above). We are analyzing the data from this morning's restart with some experts from Jive Software, and we continue to monitor performance closely.
Meanwhile, please report performance behavior you are seeing.
