Performance testing of WiredTiger independent of MongoDB is subject to significant variation in performance (just like MongoDB). This happens even when the changes are unrelated to the code path being evaluated. SEE WT-13298
Binary layout is known to impact performance.
Evaluation of tools for LTO (link time optimization) like LLVM or Meta's BOLT as they should in theory provide stability to the binary layout.
In addition improved performance could be a no cost benefit.
It is important to note that this LTO would be for WiredTiger testing, etc. Propagating any LTO into the server build necessarily requires consultation with server and is an explicit non-goal for this ticket.
