Description of problem (please be detailed as possible and provide log
snippests):
ODF v4.13.0-186 shows poor read performance at 128/4096 block sizes with on-wire encryption enabled vs. disabled in FIO tests. We see this for both RBD and Cephfs storage classes. We are measuring IOPS
I am using FIO with 50 servers, numjobs 4, and this relates to 128 and 4096K block sizes. The spreadsheet showing this degration is here:

Can this issue reproducible?
yes
Can this issue reproduce from the UI?
If this is a regression, please provide more details to justify this:
Steps to Reproduce:
1. configure ODF storagecluster w/ on-wire encryption disabled
2. run FIO tests are 128 and 4096K block sizes as described above
3. capture IOPS and other info in perf dashboards
4 re-start same 3 steps w/ on-wire encryption enabled
Actual results:

This bug having no release flag set previously, is now set with release flag 'odf‑4.14.0' to '?', and so is being proposed to be fixed at the ODF 4.14.0 release. Note that the 3 Acks (pm_ack, devel_ack, qa_ack), if any previously set while release flag was missing, have now been reset since the Acks are to be set against a release flag.

This looks like a candidate for the core team (messenger) to look into first (especially since the behaviour experienced is same for cephfs and rbd).
