Re: L2 is filled from HDD instead of L1 cache
Maybe give the user option to set idle speed as well as idle detection. I'm confident that my ssd can handle a lot more than that. especially if queue depth is bigger - as in this case -you should write groups of blocks at a time, not a single block. all disks benefit from knowing what's next to wri...

Re: L2 is filled from HDD instead of L1 cache
Please note that in order not to affect other applications' tasks, PrimoCache is set by default to fill L2 data when the source disk is idle. Even with INSTANT gather level, maximum L2 fill rate is limited to 40MB/s. We are talking about 0.5-1 MB/s. The L2 disk was not used for anything else. Yes, ...

A problem when data is partially cached
I just tried caching a 500GB HDD with 60 GB L2 cache. The L2 cache read speed is 2000 mb/s. I left it for two days working and 50 GB of the cache was filled. the program was hitting 90% cache. Then I decided that it's too slow so I bought ssd. During the copy I froze the cache so it doesn't fill it ...

L2 is filled from HDD instead of L1 cache
Hi, I have a problem. I'm trying to speed up a 500 GB HDD. I gave it a 66 gb NVME L2 cache (INSTANT) and 1 GB L1 cache (block size 8k). The HDD is being accessed at relatively low speeds. The average is between 600 and 900 kb/s. The ssd has 20-40k iops and reaches about 168MB/s write speed at 4k, qu...

PrimoCache writes more L2 cache than the volume is big
Hi, Primocache still has one big problem. If I forget to pause/freeze the cache and I copy big files (in this case 300GB) Even though the L2 cache volume is only 100GB and at the end of file copy 30 GB were written to L2 cache it kept going and wrote >300 GB to the 100 GB partition. it would be nice...

primo cache writing more data at once than the L2 cache size is
Hi, I have 16GB L2 cache for my HDD. I was copying files and I forgot to turn off cache. I saw that L2 storage write is at about 1 GB when I turned off the cache. The total read was about 28GB. So I turn off the cache, but then the cache starts flushing. At the end 25 GB was written to L2. Why would...

I was trying to see the meaning of each gather interval option, but it's not in the help info: https://www.romexsoftware.com/en-us/primo-cache/instructions-create-cache.html Could you update help so it contains all the dialog and the options with their meaning. For example I could find info on what ...

primocache 4.2.0 Hanging on delete cache volume
I wanted to remove a volume from cache task, but keep the cache task. I right-clicked, then delete cache this volume and a progress bar appeared and never stopped. It's been 10-15 hours, so I think the program is hanged. I can't close it and I'm afraid to restart. And I have another question. Can yo...

Re: How far in the boot process does primo cache kick in
So in theory after a few boots all the parts of windows (except maybe HDD drivers) will be in L2 cache?

How far in the boot process does primo cache kick in
Hi,
I want to accelerate windows boot partition with primo cache and L2 SSD. Currently I cannot boot from NVME SSD, so I wonder how effective will be L2 during boot process. Does it start working on boot (like for example HDD drivers) or before login or after login
