Public bug reported: This is to consider/discuss the possibility of whether the Ceph packages (UCA) should be built with RelWithDebInfo build option (CMAKE_BUILD_TYPE [0]) which can be supplied to the build script do_cmake.sh [1].
Currently, Upstream as well as UCA builds default to 'Debug' [0] builds. But is any reason why shouldn't go for RelWithDebInfo (i.e. "Release with Debug information")? There's one issue noted with RelWithDebInfo which has a workaround too [2]. In general, gcc's -O2 [3] build should generate better code as well as there's a specific case for Ceph [4] that it improves performance.
