wsrep API v26 has separated replication call into separate certification and commit steps. With that, it is possible to support binlog group commit, and this has been done in the MySQL version. however, MariaDB has different group commit logic, and remaining work is to make sure that the integration work done so far works and group commit really "kicks in". |

Will the performance benchmarks also test different values for binlog_commit_wait_count and binlog_commit_wait_usec? https://mariadb.com/kb/en/library/group-commit-for-the-binary-log/#changing-group-commit-frequency |
