I was reviewing some documentation which includes: Redhat for example has a very optimal tool chain which they use for their Enterprise product line and it is not available to other distributions (or rebuilds) and thus their resulting binaries and libraries have been more performant then other Linux distributions we have tested. Can someone say if that's correct? I assumed building was done similarly to koji. (I could experiment, but it seems better to ask where someone presumably knows, assuming they can say.)
