The idea is make possible to nodes to cash some frequently reeded files of node on fast drives possible. This will make hot files possible to read very fast from nodes. Also node will make less seek operations and make faster response on writes. Like every HDD have cash for better performance. I…

This is supported with LVM in linux, ie if you have an LVM layer with your FS on it. See lvmcache(7) - Linux manual page and similar pages. I haven’t tested this at all myself so I don’t know if this yields any actual performance gains for this use case.

My HDDs read at 200MB/s and my gigabit connection is 119MB/s. You have some fast internet if thats not the bottleneck.

[image] LrrrAc: My HDDs read at 200MB/s and my gigabit This is only meaningful for a sequential read of a very large files located on the outer tracks of your drive. When random access is involved (e.g. small files, especially scattered across the disk) it is not unusual to see as low as 0.01…

Since you uses Windows, you can try to use Windows Storage Spaces and their cache capability: [image] Looking for help to set up RAID6+Dual SSD cache Node Operators The cache is available on server version of Windows See also [image] GitHub - freemansoft/win1…

I found software that makes this cash in RAM or SSD. I tried for now make it on NVME.

OK now after some day I have some statistiks. About use of cache. I made on 8x 4TB nodes cach NVME 1 TB shared for read/write. this is statistics about in weekend started on friday, first 24h filewalker made hdds working 100% Volume Node4 (J:) 2022-09-05 12:55:03 Total Read 228.38G…

But does it give you a higher success rate compared to an uncached node?

Primocache with huge load corrupt my files and i lost some nodes. Be careful with this soft

did you used RAM cache or NVME?

Is it possible to make read only cash for node, to serv hot files?
