Slow Response Time

Hi,

I am running MariaDB 11.4.2 on RHEL 8.2, my database is very slow is responding, i have even increased value of memory parameters like innodb_buffer_pool_size , key_buffer_size , query_cache_size, join_buffer_size, sort_buffer_size and some more,but response is still the same (not even one second execution time difference), can someone help me sort out the issue?

There are many possible reasons. You've identified slow queries, so next you could use EXPLAIN (EXTENDED) on these queries, see what the optimizer plan is, whether they're indexed properly. Most causes of slow queries are problems with indexing.
