Performance Issue with CPU Processing In Exalogic X4-2 Virtual Racks (Doc ID 1925546.1)

Last updated on AUGUST 13, 2018

Applies to:

Exalogic Elastic Cloud X4-2 Hardware - Version X4 to X4 [Release X4]
Linux x86-64
Oracle Virtual Server (x8-64)


In Exalogic X4-2 racks running Virtual releases 2.0.6.x, in few of the compute nodes performance issues with CPU processing speeds is observed.

This issue can be verified using following commands:

dmidecode -t processor | grep "Speed"
cat /var/log/dmesg | grep "MHz processor"
cat /proc/cpuinfo | grep "MHz"
time echo "scale=10000; 4*a(1)" | bc -l

Above command outputs shows CPU processing speed in MHz. Below is sample output for reference

       Max Speed: 2933 MHz
       Current Speed: 2933 MHz 

On the problematic nodes we see the CPU processing speeds are varying more than 10 seconds when compared to nodes which do not have issues.
