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.
