Here are the recommended settings for an **8 GB RAM VPS**: ```ini [mysqld] # InnoDB settings # Set to 50-70% of total RAM. innodb_buffer_pool_size = 5G # The number of threads writing data from the buffer pool to the disk. # A good starting value is 4 for modern systems. innodb_io_threads = 4 # Amount of memory for the log buffer. # A larger value can improve write performance for big transactions. innodb_log_buffer_size = 32M # Query Cache settings # Recommended to disable since MySQL 5.7+ and deprecated in 8.0. query_cache_type = 0 query_cache_size = 0 # Connection settings # Maximum number of concurrent client connections. # Adjust based on your expected traffic. max_connections = 300 # Other settings # A temporary table size limit to prevent memory exhaustion. tmp_table_size = 128M max_heap_table_size = 128M ``` ### Key Changes * **`innodb_buffer_pool_size`**: Increased to **5 GB**. This gives the database significantly more room to cache data in RAM, which drastically improves the performance of both read and write operations. * **`innodb_log_buffer_size`**: Increased to **32 MB**. This improves performance when processing large write transactions. * **`max_connections`**: Increased to **300**. This allows your database to handle more concurrent connections, which is essential for a busy website or application. * **`tmp_table_size` and `max_heap_table_size`**: Increased to **128 MB**. This can improve the performance of complex queries that use temporary tables.
