On Linux, there is the concept of “ionice”, which is to I/O what “nice” is 
to CPU usage. So for example if updatedb had its ionice dropped to “idle” 
priority, that allows it to be pushed to the back of the queue when 
regular apps need to do any I/O. Result is much less system impact from 
such background update tasks.

Maybe there’s an option to set this somewhere?
