Cost Threshold for Parallelism (CTfP) is one of my favorite server level settings in SQL Server. I remember the first time I heard this setting mentioned by Grant Fritchey. I quickly hopped on my servers and found them all set at the default (5) and adjusted them to 50 for the non SSRS servers and 30 for the SSRS ones. That was many years ago, but I had kept those numbers in my head because I didn’t know a better way.
