Re: Free Cache (L2) seems too small?

Welcome to the forums EmeraldMonkeyPaw, You should only expect to see the full amount reported as free at the very start of caching. Having only a small amount left means that your cache is being properly utilised - try Stopping the cache task to see what effect that has on performance. Deleting/rec...

Re: Need Advice on Very Low Hit Rate

The caching works absolutely awesome on the HDDs, without looking at the numbers I can notice a huge improvement just by using it. However, I only get about 10% hit rate on the D: drive and below 1% on C:. I used all default setting except changing block size to 16KB. Is this what I should get or i...

Re: Request for P.Memory Exceeds the Amount Currently Available

Joshua, The attachment makes it clear that you are not using any invisible memory (free=total) and that your ramdisk is instead using "standard" (managed) memory - see attachment below for the type of figures to expect from an IM ramdisk. You clearly have PAE/DEP set up (required for IM to...

Re: Request for P.Memory Exceeds the Amount Currently Available

Welcome to the forums Joshua, It looks like your ramdisk is currently configured to use main memory only. After specifying the size of the ramdisk, you should have a second configuration page which contains a checkbox (under Physical Memory Settings) labeled "Use Invisible Memory" - this n...

Re: Level 2 cache not increasing speed

Well, the reason for using Atom is simply low power consumption...This server costs me around 6 dollars a month / 74 dollars a year. I built it well over a decade back....so that has cost me $740...a current generation machine will suck up much less power...but I will have to spend around 500-800 b...

Re: Level 2 cache not increasing speed

Any thoughts? Just that you seem to have spent quite some time confirming the points made above - that the SATA connection of your SSD is not an issue, that your CPU is the bottleneck and that L1 cache is not worth enabling unless you can dedicate significant memory to it. I do wonder why you are s...

Re: temp location changing every reboot

...i can see it change within the app using the utilities but upon reboot windows just changes it back to C drive Windows updates have a habit of resetting the Temp folder so if you have one that isn't completing but trying to rerun every Windows startup, this could be the cause. In such a case, ZD...

Re: Level 2 cache not increasing speed

As you spotted, running a network test results in a network bottleneck (1Gbps Ethernet is unlikely to exceed 80MB/s - you may be able to tune yours to offer better performance by checking the Jumbo packet settings if you haven't done so previously). Your setup only allows 128MB for L1 which is point...

Re: Best settings for cache?

Welcome to the forums Aaron, In this situation, if i enable "Lock Cache Content" does those AV signatures gets loaded from the file when PrimoCache writes to a disk when shutting down or rebootin? Enabling pre-fetch does not result in actual data being stored, but instead the block numbers...

Re: Caching Policy/algorithm suggestion:

From research paper: Differentiated Storage Services by Intel Labs...So I'm guessing a LFU algo, but evict large I/O 1st algo It's an interesting link and highlights an issue with how large files can have a disproportionate effect on caching. The problem for PrimoCache at the moment is that it runs...
