CPU load spike analysis

[anandbpillai]

Hi team,

We are conducting the performance test (using MIBGET block) on the application on below EVE setup details.

Soft dPAC with Archive database

Local Test simulation

Version 22.0

In the attached report, we are getting many peaks in CPU Load as seen in the report. We want to know proper reason for this spikes by using some details so that we can improve them or How to identify these spike reasons in EAE.

Pls suggest.

Hi anandbpillai,

can you provide your application so we can reproduce ? On which IPC are you running (CPU/Ram) ? which Linux Distro ? do you have a Real Time patch applied ? if not can you redo the test with a patch ?

It is difficult to know why you have this spike without further investigation.

hi @KarimBenameur ,

I have attached the solution for your reference. We are not testing on any hardware but on the cloud VM using EVE setup by using Local Test simulation.

Also what is real time patch ?
