It sounded like he was on a not too fast computer that might bog down if it had to scan 10G all at once -- might even take 5 seconds!
In fact it is on an extremely fast 16 core with oodles of RAM. The processor is not taxed by all the activity.
Oi...It's NOT going to be changed by tweaking XFS vars. XFS isn't what is holding it in memory. It's the kernel.
The suggestion was from the XFS list. But the variables to tweak are VM.
Linux is saving up scanning for more memory for all at once, as it is more efficient that way.
You can play with values in /proc/sys -- but it will all be a kludge, as what you really need is to avoid the cache altogether.
Or just find a way to keep it from thinking that all that tasty RAM is available for it's evil purposes :) The cache system needs to curb RAM intake. Go in a diet.
