Hi Ortis, How abt the hits or load i.e ( DML, DDL ) to the server. My initial assessment after looking at you cnf file is 1) Calculate and place an appropriate value for innodb_buffer_pool_size 2) Reduse the innodb_thread_concurrency to 4 or 8.
and how about the no. of tables in the database and the table type.
