What is the size of L2 cache writes? Is it equal to the set block size? Or some other constant?
I'm asking because currently when I have block size set to 4KB the writes are slow: 16MB/s when Task Manager says the SSD is 100% busy. There must be something suboptimal about it, maybe the writes are too small? For L2 populating you could gather many blocks and write in several MB big bursts.
If there are many block-size write requests it could be beneficial to increase the block size to reach more optimal speed vs overhead ratio (SSDs have natural write overhead anyway).
Size of L2 writes
Re: Size of L2 writes
PrimoCache has its internal parameter to decide the L2 write size. It is not equal to the block size. I think you get slow L2 populating speed just because PrimoCache think your computer is busy. You may try a fast "Gather Interval" in the L2 advanced settings.
Re: Size of L2 writes
Populating speed is ok, writes itself are slow (and can't be faster the way they're done as disk's active time is 100% then).
Re: Size of L2 writes
You mean the L2 writing cache? The speed that writing from L2 storage disk to the underlying HDD disk?
Re: Size of L2 writes
No, writes to SSD are slow (L2 population and L1 deferred writes). When PrimoCache writes to SSD, task manager shows 100% SSD activity but 16MB/s speed.
Re: Size of L2 writes
Is the SSD cache almost full?
Re: Size of L2 writes
Yes but it also happened when it was fresh.
Re: Size of L2 writes
So if you use a bigger block size, you get a better write speed?
The write speed from Windows/Applications to L2 is related to source data incoming speed as well as L2 disk native write ability.
