PEBS

When I run the PEBS on the intel Syklake and then run the pref concurrently I have found that number of micro operations delivered from microcode sequencer (MS) is increasing a a lot. Particularly by lowering the sampling rate of PEBS it grows exponentially. Can we say that these micro operations delivered from the MS  are related to running the PEBS assist microcode on the core ?

The model is "Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz" and I want to measure the PEBS overhead while running the workload.
