It seems to be JITting the generic binary code.
Would these same gains be seen from compiling MySQL for the actual target architecture gentoo-style e.g. -farch=native ?
- viraptor 9y agoIt looks like it's taking measurements from live process, so probably not arch=native. But most likely the runtime profile guided optimisation would do a similar job.
