Hi, when I said folder it means that I copy a single folder (with a thousand of files inside it), when I said "lot of files at the same time" it means that I select all files inside the folder and I copy them and not the parent folder. Every operation is made from an iMac with MacOS 11.6.1.

UPDATE: the issue occurs only if I upload lot of files at the same time (1200 pictures inside a folder), if I upload the folder (and not the files inside it) transfer is at the max speed (6 minutes for 48GB). If I try to transfer all the pictures in a folder with a thousands more photos the transfer is incredibly slow (8h for 48GB)

Thanks for the reply. In this scenario the cache drive is "Cache_ssd_nvme" that is a Samsung_SSD_970_EVO_Plus_500GB. I've used this drive as cache for three weeks before that issue comes and the issue still even if I set ssd drive to No in the share's settings (after invoke the mover). This is the screen of the top during iPhone pictures transfer (hardware is i3-7100 CPU @ 3.90GHz, 16GB RAM and 1gbps LAN)

I'm noticing that issue occurs during transfer lot of files in a folder with thousand files inside, there are no problems in a single file of few files transfer.

There is no operation running in the array and mover runs at 3:40am every day. I'm using cache drive since a month with any problem but yesterday I uploded to a smb share a lot of files inside a single folder, transfer is running since yesterday for less than 50GB...unusable!

Hi, I’m running Unraid 6.9.2 and I’m having an issue to upload files to a quite big folder (2000 files). Uploading 1700 files (25GB) takes over 3 hours from Mac. Top command shows me shfs process with very high CPU usage!! How can I solve this? Best regards
