Update : Tried with the Btrfs and got the same results. Tried with a hardware raid, single vdisk in unraid (no parity nothing) and got the same results. Found out this thread : https://www.reddit.com/r/unRAID/comments/t1m15r/unraid_is_terrible_for_users_with_tons_of_files/ and figured the issue is in the core of Unraid with the FUSE system and there is not much that can be done to improve. I feel even the upcoming Raidz will not solve this read performance issue. This is sad as I realy like the Unraid docker system, but I feel I will never have good user share performances for my needs.

Using the "Disable security mitigations" pluging did help a little bit on the performances. I have measured an improvement of 15%. I feel that confirms the issue is with the CPU algorithms and not the disks. I am still open to suggestions but I have the feeling this will be the unraid system performances and not much can be done to improve.

Looking for help improving user share read performances. I Noticed read perfromances issues in this fresh new unraid installation. Listing the content of a user share is much slower then reading the content of the disk share containg the data. The array has 1 parity disk and 3 data disks. I did not configure a cache disk yet. System is dual xeon E5-2660 with 64gb ram and is mostly idle and unused. The test is done on a the unraid server cli interface with a share folder containing 56k files for a total of 44gb. Here is some test comparing the user and disk performance. The command used for tests is : "time du -h ." and was executed twice for each test to allow for system caching. root@Vault:/mnt/user/Archives/emy# time du -h . [...] 44G . real 0m13.703s user 0m0.285s sys 0m2.161s The result on the disk containing all the data : root@Vault:/mnt/disk3/Archives/emy# time du -h . [...] 44G . real 0m0.221s user 0m0.079s sys 0m0.140s I tried installing the "Dynamix Cache Directories" plugin and did not see any improvement. Is there someting I forgot to configure in the system or any idea on optimization settings I could try?
