If jitterentropy-read from CPU jitter is used in all cases, a big performance problem is seen for most cases where BIG-IP works in non-FIPS mode. This can be encountered after upgrading to version 17.x from an earlier BIG-IP version.
Very high CPU utilization is seen when BIG-IP handles traffic while in non-FIPS mode.
The issues occur when BIG-IP operates in non-FIPS or FIPS mode and use jitterentropy to generate seed.
