L2 cache never gets written or used on reads
Posted: Sun Feb 09, 2020 4:30 pm
I do a lot of heavy reads on slow hard drives (video editing) and almost no writing.
I have my L1 and L2 cache set to not have individual areas for read and write. However, I notice that nothing ever gets written to the L2 cache when I am reading from the HD. It will write to L1 cache and then later reads will be fast but nothing ever goes onto L2.
It will go onto L2 if I turn of L1 cache, but this seems silly. Is there a way to get both L1 and L2 cache to hold store data in cache while I am doing big reads?
Thanks
