[17:13] <EricLopez> Noticed a behavior change with swapper starting with kernel 6.5.0. Swapper overhead is over 70% on x86_64. This behavior is not exhibit with earlier kernels or on aarch64.
[17:13] <EricLopez> Example:
[17:13] <EricLopez>  Overhead  Command          Shared Object
[17:13] <EricLopez>   78.84%  swapper          [kernel]
[17:13] <EricLopez>    6.58%  data-plane-kafk  [JIT] tid 609
[17:13] <EricLopez>    4.69%  data-plane-kafk  [kernel]
[17:13] <EricLopez>    2.04%  ReplicaFetcherT  [JIT] tid 609
[17:13] <EricLopez>    1.48%  ReplicaFetcherT  [kernel]
[17:13] <EricLopez>    1.01%  data-plane-kafk  libz.so.1.3.0.zlib-ng
[17:13] <EricLopez>    0.49%  C2 CompilerThre  libjvm.so
[17:13] <EricLopez> but on 5.4, 5.15, and 6.8(aarch64), it is typical similar to this
[17:13] <EricLopez> Overhead  Command          Shared Object
[17:13] <EricLopez>   19.72%  data-plane-kafk  [JIT] tid 1818606
[17:13] <EricLopez>   15.01%  C2 CompilerThre  libjvm.so
[17:13] <EricLopez>   14.12%  data-plane-kafk  [kernel]
[17:13] <EricLopez>    8.08%  swapper          [kernel]
