How CPU L3 Cache Difference Makes the Coherence Members’ Performance Does Varies in the Cluster?

Oracle Coherence - Version 12.1.2.0.0 and later
Information in this document applies to any platform.

Goal

A CPU cache is a smaller faster memory used by the central processing unit (CPU) of a computer to reduce the average time to access memory. L1 (Level 1), L2, L3 cache are some specialized memory which work hand in hand to improve computer performance.


In the customer's case a setup of two clusters - Cluster A and Cluster B - both have similar settings but the performance of Cluster B is 30% slower than Cluster A. The only difference in system configurations is CPU L3 Cache. It is 25600K for Cluster B while it is 40960K for Cluster A. Can this be the reason for performance issue between these coherence clusters?
