Something VERY different about buffered write mode

Yesterday and today I had to transfer about 4 Tb of data with around 2 million files from one USB3 drive to another. I did so using robocopy with only 1 thread (MT:1). It was only an 8 Gb system so I set up two cache tasks for 2 Gb of L1 read/write on each one. I have done a lot of copying to USB dr...

Re: Primocache and Network File Transfers

No, when you call the data to be read, it will not be automatically copied to the cache and then moved across the network. Copying to the cache upon read is a post read process. This is set in the gather interval. It cannot predict what you need to read, it can only see what you have read. Of course...

Re: Primocache and Network File Transfers

Yes it will but unless you have a very large amount of RAM, whatever nominal amount you set to L1 cache will rapidly fill up, it will then divert the data to L2 cache or directly to the spinner with urgent writes, depending upon your settings. In this case if you do have L1, then set flush L1 cache ...

Re: Primocache and Network File Transfers

It will speed up network files transfers only if the data you are copying is already cached in L1 or L2 since your network connection is not the rate limiting factor. Your problem with these large files is that they would need to be cached which would mean that they would need to have already been p...

Re: primocache 4.2.0 Hanging on delete cache volume

Happened with me as well. I've spent hours trying to recover full usage of various SSDs/HDDs to no avail. Is there a solution to simply "reformat" the SSDs/HDDs I was "tinkering" with during the trial process as to completely remove any residual effects from the Primocache appli...

Advice for users about Windows memory compression

I would like to give PrimoCache users some advice about a Windows 10 and 11 feature that, depending upon your PrimoCache configuration, is unnecessary. In fact, if this feature is active it will actually reduce your performance by causing occasional brief lags as you use your PC. That item is Window...

Re: Any way to limit defer-write speed/utilization?

You are very courageous letting data sit in a cache for that long! Probably the closest you can get to what you are trying to do with the current feature set of PrimoCache would be set an infinite write delay and Idle-Flush. This way it will only flush if the system is idle and as far as I understan...

Progress Indicator on Processing Please Wait in Config Screen please

Today I made a change to the cache while there was 150,000 blocks still to be written to a USB2 drive. Of course it needed to flush the data which of took forever on the USB2 drive. It would be nice to have a progress indicator on that screen when it does need to do a flush in a situation like that....

Re: primocache 4.2.0 Hanging on delete cache volume

Yes this has happened to me a few times also. With me it occurs when I reset the cache content.

Re: What happens with L2 in this situation

Thanks. What if free cache on written is selected? Will it mark the blocks in both L1 and L2 as standby or just L1?
