sorry for the delay. I had missed this one.
The change looks feasible to me.
It may only impact the utilization of the Code Cache. Can you evaluate that (e.g. by running large benchmarks with -XX:+PrintCodeCache)?
Thanks and best regards,

Please review a change for JDK-8188131.
Bug report: https://bugs.openjdk.java.net/browse/JDK-8188131
This change increases the default values of FreqInlineSize and
InlineSmallCode in ppc64 to 325 and 2500, respectively. These values are
the same as aarch64. The performance of TPC-DS Q96 was improved by about
6% with this change.
