Evaluate using Profile-Guided Optimization (PGO) for optimizing the IKV performance

[zamazan4ik]

Hi!

I collect materials about applying Profile-Guided Optimization (PGO) to different applications in different software domains - all my results are available at https://github.com/zamazan4ik/awesome-pgo . According to my tests, PGO helps with achieving better performance in different areas, including many databases.

I think it will be interesting to see PGO results for IKV in benchmarks since according to my tests, even Redis performance can be improved with PGO (the results are available in the repo above).

Please do not treat the issue as a bug - it's an improvement idea.
