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...

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

Re: Compression (with an option to turn it on/off) for cache data

I agree It's not easy - but it does take an effort to make something good. Currently L1 cache does not offer much more than windows cache. Compression would be a big advantage. There are open source libraries for most compression algorithms. You could add a compression type attribute to blocks - lik...

Compression (with an option to turn it on/off) for cache data

I want to request compression (with an option to turn it on/off, choose algorithm) for cache data (not meta data). ZFS is using compression for it's cache with near zero impact on performance/cpu usage with LZ4 compression - a really high speed algorithm. I don't know what's the license for it, but ...

Re: More Detections

I don't know how possible it is to cache network drives (like samba), but caching on the remote computer doesn't do much. If I share RAM drive it's still slow for small files. The bottle neck is the protocol. I don't know why, but it's extremely slow accessing 1000s of small files - like 10 to 100 t...

Re: Problem with prefetch v3.0.2

ok, but what about the option to not fetch from more than one partition of a specific physical drive at a time?

Re: Non-deferred write cache

So if the user expects most of the written data to not be read (like log files), then he shouldn't enable write cache. If he expects that soon the written data will be read again (like temporary tables of database) then write cache could be enabled.
