[Service] Environment=LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libtcmalloc.so in the mariadb service file. Or, if you use mariadbd-safe, [mariadbd-safe] malloc-lib=/usr/lib/x86_64-linux-gnu/libtcmalloc.so it's all documented here: https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/compiling-mariadb-from-source/compiling-mariadb-with-extra-modulesoptions/using-mariadb-with-tcmalloc-or-jemalloc > For reference, the filelist of the jemalloc and tcmalloc development > libraries in Debian: > https://packages.debian.org/sid/amd64/libjemalloc-dev/filelist > https://packages.debian.org/sid/amd64/libgoogle-perftools-dev/filelist Regards, Sergei Chief Architect, MariaDB Server and secur...@mariadb.org _______________________________________________ developers mailing list -- developers@lists.mariadb.org To unsubscribe send an email to developers-le...@lists.mariadb.org
