Unexpected CPU utilization on LTM
Hello I am testing 2 different LTMs(VE) and would like to compere the CPU performance to select CPUs for our customer enviroment. BIG-IP 12.1.1 Build 0.0.184 Final 8core BIG-IP 13.1.1 Build 0.0.4 Final 12core During that load testing(1000TPS for SSL), I noticed that the CPU usage of Lower version LTM(8cores) is at 40%, but higher version LTM(12cores) is at 50%. I expected that 12 cores LTM had lower consumption of CPU than 8cores, these results were completely the opposit. Could someone tell me why did that turn out like this ? Thanks in advance for the help.
Relation between CPU , core and TMM
I have a doubt between CPU , core and TMM. I read that CMP feature allows platforms that contain multiple CPUs to run a single TMM process for every CPU, and multiple TMM threads per processing core. So i have a VIPRION 2250 blade which has : Cores per slot is 20, running only 1 VCMP guest and only 1 slot. According to https://support.f5.com/csp/article/K14358 , we have the below: 1 Deca-core (+HT) - Processor 1 - TMM processer 10 - TMM threads (11.5.x) tmsh output shows 10 separate TMM instances (threads) running Questions: 1. In the device above how does TMM process, TMM threads, processor and CPU collaborate? 2. I also see in the performance tab in CPU Utilization , I get 4 graphs with 4 core each, how is this calculated? Thanks!
