I wanted to give an update on VMware Communities performance. Overall, we have been seeing some intermittent slowness again this week, and we are working on a couple of areas to address it:
1. Networking errors: We have identified and are in the process of debugging some networking issues between the two nodes in the cluster.
2. Private network: We are currently testing and plan to roll out a private network between the two nodes, which will increase the transfer rate of cluster information between them.
3. Automatic restarts: From early December until mid-January, the communities application ran with consistent performance, but then started slowing down. This problem was resolved when we rebooted at the operating system level, which makes us think there is a resource leak. We are therefore implementing an automated restart at the operating system level on a periodic basis.
4. Resourcing: We are putting additional Java experts on these problems to get them fixed quickly. Performance and system stability is the top priority.
We've had system monitoring in place since early December, which includes automatic restarts of the application when performance thresholds are reached. And the root cause analysis that we do at every application restart consistently is pointing us at the issues listed above.
