The cache seems to be working but the stats for free L2 cache don't seem to be working correctly.
If I've read 22 GB shouldn't there be about that much minus L1 Cache in the L2 Cache?
According to the stats below I have about 7GB in my L2 cache.
my l2 cache is a 128GB SSD with a max partition.
My l1 cache is 4GB with a block size of 32KB.

In the previous version I would see the L2 cache fill up over time.
Its hard to tell but it doesn't seem to be doing that.

Code: Select all

Volume 1TB (L:)

Most likely the cache read is from the L1.

blocks expiring from L1 get moved to L2. Correct?
Therefore I should see L2 grow over time

Cached Read is combine read of cache both for L1 & L2. L2Storage cache is for L2 only. You should only needs to concentrate on the L2 Read, as that the data being cache on the SSD.
