Hi, A 16MB key buffer seems very small; this is OK for a personal workstation with 64/128MB RAM not for a high performance 1GB server.
If your queries are using indexes, you should check Key_read_requests and Key_reads values, if your query buffer is efficient, Key_read_requests should be MUCH greater than Key_reads. As an example, here are the values from our main MySQL server: | Key_blocks_used | 186985 | | Key_read_requests | 3214556494 | | Key_reads | 183458 | If you want to optimize Key_buffer parameter, you should evaluate the size of all your indexes (check *.MYI sizes) and use this value as a starting point.
