But the root cause was just a missing Non-Clustered Index.

During my various consulting engagements and SQL Server Health Checks, I always recommend a Cost Threshold for Parallelism of at least 20 or even 50.

A recommendation is to set the Max Degree of Parallelism to the number of cores that you have in one NUMA node.

Therefore SQL Server tries to keep parallel plans in one NUMA node during query execution which also improves performance.

With an address space of 48 bits you can address up to 256 TB of memory – that’s still a huge amount of space.You should always change this configuration option, so that you also give your OS some memory to live and breathe.Normally (without any other programs/processes on the server) you should give the OS at least 10% of the physical memory.Therefore SQL Server tries to parallelize your execution plans too soon.But parallelism only makes sense when you deal with larger queries – like in a reporting or Data Warehousing scenario.

And as I have already covered in a previous SQL Server Quickie, CXPACKET waits are not an indication that you have problems with parallelism in your system!
