It isn't a problem - just an idea of how the project performance can be improved.
Describe the proposed solution
I checked various compiler optimizations (like Link-Time Optimization (LTO) and Profile-Guided Optimization (PGO)) on many projects (including many databases like PostgreSQL, MongoDB, SQLite, ClickHouse, etc.) - all the results are available at https://github.com/zamazan4ik/awesome-pgo . Since such optimizations help with optimizing such projects, I think it can be an interesting idea to optimize the Rust parts of Chroma with LTO and PGO.
I can suggest the following ideas:
Enable LTO. It should improve the binary size and can improve the project's performance "for free". It can be enabled only for Release builds.
Perform PGO benchmarks with some typical workloads. If it shows improvements - add a note to the documentation about possible improvements in the database's performance with PGO.
More intensive testing Post-Link Optimization techniques (like LLVM BOLT) would be interesting too (Clang and Rustc already use BOLT as an addition to PGO). However, I recommend starting with the usual PGO since it's a much more stable technology with fewer limitations.

I would be happy to answer all your questions regarding LTO, PGO and PLO.
