Key_buffer_size + (read_buffer_size + sort_buffer_size) *max_connections = 458624 K Read_buffer_size: Is the MySQL read into the buffer size. A request to sequentially scan a table allocates a read buffer, which is allocated a memory buffer by MySQL. The read_buffer_size variable controls the size of this buffer. If the sequential scan request for a table is very frequent, and you think that frequent scans are too slow, you can improve performance by increasing the value of the variable and t

Therefore, for the existence of around 4GB server recommended set to 6-8m. record_buffer=16m//Each thread scanned by a sequential scan allocates a buffer of this size to each of its scanned tables, which can be set to more than 2M Table_cache = 512//Opens the number of tables for all threads.
