How many rows are deleted? Do you use triggers?

Are you using only one connection to the database? If the answer is
yes, then that would be your answer. When connecting to Classic,
Classic will spawn a new single-thread process for each connection.
So, a single connection will only run on one virtual CPU and not use
all four virtual CPUs. So what you are seeing is one Classic instance
using CPU time on one virtual CPU.

None.
