Hi i have a large insert process that starts off rapid taking 15% of the cpu time,  but after about 4 hours it then goes down to 1.5% processor time,  is there a setting / failsafe in MYSQL that will mean a mysql process will use less processor if it has been running for x time ?

Thanks ?

In answer to the question no.
What is this a cron job or something, what kind of insert?

You might be better off doing a LOAD DATA which will be a lot of faster than manual inserts

Using PHP will always be slower, and could possibly be you are running low on memory.
How is the php coded for the inserts?
If you are looping and passing the insert statement each time then it will be slow, look at prepared statements.
