[Engine-devel] Updates in VdsUpdateRuntimeInfo

Hi all, I'm checking performance for VdsUpdateRunTimeInfo. Naturally, much of the performance surrounds database activity (getVmsRunningOnVds queries, updateDeviceRuntimeInfo, updateVmDynamic) Few questions: 1. I have implemented batch updates for procedure UpdateVmDeviceRuntimeInfo for improved performance. 2. Seems like the only parameters UpdateVmDeviceRuntimeInfo is getting are vm_id,vm_device_id,address and alias. Are those rapidly changing, or will it be beneficial to implement caching on those updates (to ensure not-required updates do not travel to the database). 3. Any additional known performance problems you know of in regards to this class? Thanks...
