** Description changed: [Impact] 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 + 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. + + Building rocksdb with optimizations enabled improves the performance and + rocksdb being an important part of OSD and MON components of Ceph, this + enables better performance of Ceph cluster. Comments #17, #18, & #19 + show relevant test results. [0] https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html [1] https://github.com/ceph/ceph/blob/master/do_cmake.sh [2] https://docs.ceph.com/docs/master/dev/perf/#common-issues [3] https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html [4] https://bugs.gentoo.org/show_bug.cgi?id=733316 [Test Case] Standard ceph-backed OpenStack regression will be run, consisting of juju-deployed OpenStack+ceph and tempest regression testing against the deployment. [Regression Potential] As Ponnuvel mentioned, the size of binaries will be slightly bigger and also the build/compilation will be longer. - Ponnuvel also did a search of pponnuvel i'd search of upstream bugs at https://tracker.ceph.com and didn't find any relevant bugs. + There are no upstream bugs for this. rocksdb is one of the submodules in Ceph and how each of the submodule gets built is left to end-users.
