These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Microbenchmark os::javaTimeMillis() on both systems.

Back in 2014, I wrote an article called Performance Tuning the Whole Query Plan. This machine has four i7 CPUs (hyperthreaded to 8) with a base speed of 2.4GHz. The optimizer chooses this plan without any hints on my system configuration because the estimated cost of the plan is below the cost threshold for parallelism.

I always check backups first when looking at a new system. Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes.
