Re: Feature Request: Disable Windows File Cache

Understood, thank you. I'd still like some way to test, but that's probably outside the scope of the software at this stage. All the tools I can find for managing the Windows File Cache are many years old, and designed for older editions like XP or W7.

Re: Feature Request: Disable Windows File Cache

Thank you for the answer Support. Do you think with faster machines and drives (i.e. recent MB/CPU and NVMe or performance SSD) that the query time would be significant enough to slow down the disk subsystem? Or could the potential gains of using 100% Cache Task queries (and no Windows cache) be ben...

Feature Request: Disable Windows File Cache

I was working on methods recently of how to force specific files into the cache using a hash calculation program (HashTools). Unfortunately, everything I fed it didn't make it into the large Primocache Cache Task I have setup, and some of it went into the Windows file cache. I understand this is nor...

Re: Is the memory type of an SSD important for PrimoCache?

2) If you can afford a separate NVMe for the L2, it would be quite a bit better due to the drive characteristics. It would of course still need to be as large as you'd planned to cover the data you wanted to cache. 3) The Total Host Writes number in Crystal Disk Info is in the upper-right area, not ...

Re: Is the memory type of an SSD important for PrimoCache?

1) If I make an SSD partition as "L2 cache", I envisage a partition of at least 300 GB to cover almost 3 TB of HDD: good plan? 2) If I take a SATA SSD, on average, it is 560 MB / s in reading and 530 MB / s in writing: more than enough? Or should you consider opting for an NVMe? 3) Where can I see ...

I was wondering, when is that update coming? It'd be quite a nice hing to have, PrimoCache is nice, but there's so much that could be added/updated...

Re: Should I dedicate an entire SSD (256 GB) as L2 cache?

I think the question in your case Strela10M, is "how much of that data will be regularly accessed?". If it is a terabyte or more, then you'll want to go for the largest SSD (as a L2) that you can. If it will be infrequent or small & highly random access, then a smaller (128 GB) SSD may do fine. Prim...

Re: Enable deferred-writes causes crashing

What kind of hardware are you working with, including the drive(s)? And what kind of writing is the computer doing after you turn on deferred writes? Also, can you screenshot your Primocache config and deferred write settings?

Thanks for the advice.

Im testing 15 and 20 seconds for defer write.
Might want to try 15, 30, and 60 for comparisons. A difference of a mere 5 seconds may not be able to give you a decent delta for results.

Re: Suggested Server settings

Server workload could be difference depending on critical data and performance required. Most raid controllers set their at 4 - 5 seconds. That is certainly possible, but you're not going to get a lot of trimmed blocks that way, especially on a server. I don't think I'd ever go under 15 seconds, ju...
