Thanks for your reply. Its clear I didn't really give enough information.
The database has many tables, some with 400 columns and 10 indices. The queries are very varied and sometimes include multiple joins. Data is added in batch a year at a time and not deleted unless the import failed, so ID and theYear are presumably are highly correlated.
ID is a primary key, and every table is also indexed on theYear as well.
I have to run myisamchk anyway as I compress the tables so it sounds like I should run it with the option to sort the data on ID.
many thanks
