Because when I ran ldd, neither tcmalloc nor jemalloc showed up. And I used gdb to set a breakpoint at one of malloc in rgw. It showed it is calling __GI_libc_malloc().I basically followed the instruction in README.md to build ceph for vstart purpose. I wonder what I missed. > On Oct 20, 2023, at 2:29 PM, Casey Bodley <cbodley@xxxxxxxxxx> wrote: > > the cmake variable ALLOCATOR can be used to request a specific > library: https://github.com/ceph/ceph/blob/f080406/CMakeLists.txt#L376-L420 > > rgw and other ceph binaries refer to ALLOC_LIBS to add that link dependency > > On Fri, Oct 20, 2023 at 2:20 PM Casey Bodley <cbodley@xxxxxxxxxx> wrote: >> >> On Fri, Oct 20, 2023 at 1:54 PM Yixin Jin <yjin77@xxxxxxxx> wrote: >>> >>> Hi folks, >>> >>> How could I make rgw built with tcmalloc/jemalloc? I had tcmalloc installed. Although build.ninja has libtcmalloc.so listed for bin/radosgw, it is still using libc’s malloc. Then I had jemalloc installed and the result is the same.
