myisamchk notes

To speed up table repairing use large values for key buffer and sort buffer. Both values can be made very large cause only one of them is used at a time.

Eg: myisamchk --key_buffer_size=512M --sort_buffer_size=512M --read_buffer_size=8M --write_buffer_size=8M ./path/to/database/table.MYI

--sort-recover, -n
