Columbus is taking time to save the configuration settings
The domain in the OS Deployment > Smart Deploy >Configure>change hardware settings, or change jobs a bit, normally the save takes about 50 seconds, so if we need to tweak 20 computers, it takes a long time.
We have analyzed the performance issue when saving the Smart OS-Deploy configuration. In our test environment, it took about 90 seconds. Please create an index in the database from the below command. After the indexing change, it took only 6 seconds.
CREATE INDEX [COOSDCONFIG_IDX1] ON [dbo].[COOSDCONFIG] ([OSDTEMPLATEID], [OSDDEVICEID], [OSDCONFIGGROUP])
We will add that database index to the official product release (will be part of Columbus 7.6.3).
