mbc0 Posted September 15, 2024 Posted September 15, 2024 Hi, I have 3 different NVME pools on my main server as pictured. All tests have been done using midnight commander. If I copy between any of the pools using /mnt/cache - /mnt/cachetwo - /mnt/Nvmepool I get 450-500 mb/s which is great, but if I copy from any of those pools to a user share I only get around 150mb/s ? I don't understand this as the shares are set to use the NVME cache pools and parity drive is not being used when writing to the pools so why are file transfers slower when writing to user shares? Any guidance would be very appreciated! unraid1-diagnostics-20240915-1036.zip Quote
JorgeB Posted September 15, 2024 Posted September 15, 2024 User shares always add some overhead going through FUSE, set the pools to exclusive if possible, and you can still use the user shares and will bypass FUSE. Quote

Thank you, so there is a reason, even though I do not know what FUSE is/is doing (I will investigate) Can you please enlighten me on the setting the pools to exclusive? I really do not know what you mean? Thank you! Quote

There is an option to enable Exclusive Share support under Settings->Global Share settings. I would suggest you make sure you read the help built into the GUI for that setting to understand when it applies. Quote
