-------- Recommendations
---------------------------------------------------------------------------
General recommendations:
Control warning line(s) into /var/log/mariadb/mariadb.log file
MySQL was started within the last 24 hours - recommendations may be
inaccurate
Enable the slow query log to troubleshoot bad queries
Reduce or eliminate unclosed connections and network issues
Configure your accounts with ip or subnets only, then update your
configuration with skip-name-resolve=1
Set thread_cache_size to 4 as a starting value
For MySQL 5.6.2 and lower, Max combined innodb_log_file_size should have a
ceiling of (4096MB / log files in group) - 1MB.
Before changing innodb_log_file_size and/or innodb_log_files_in_group read
this: https://bit.ly/2TcGgtU
Variables to adjust:
SET innodb_stats_on_metadata = OFF
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
thread_cache_size (start at 4)
innodb_file_per_table=ON
innodb_log_file_size should be (=16M) if possible, so InnoDB total log
files size equals to 25% of buffer pool size.

Jean,
How is that MariaDB instance configured? As a quick-and-dirty first
approximation, what does mysqltuner tell you?
