Here are the recommended settings for an 8 GB RAM VPS:

[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.
