[Slow SMB performance]

I had i9-9900 32 Gb with 10Gb ethernet. Same issue with small files (TimeMashine, Apple Photos lib, etc.).

Could it be this has something to do with old SSD write issue? Did you already reformat your NVMs if any?

Also, "Case-sensitive names: Auto"  makes significant performance hit with directories with many files:

Controls whether filenames are case-sensitive.

The default setting of auto allows clients that support case sensitive filenames (Linux CIFSVFS) to tell the Samba server on a per-packet basis that they wish to access the file system in a case-sensitive manner (to support UNIX case sensitive semantics). No Windows system supports case-sensitive filenames so setting this option to auto is the same as setting it to No for them; however, the case of filenames passed by a Windows client will be preserved. This setting can result in reduced peformance with very large directories because Samba must do a filename search and match on passed names.

A setting of Yes means that files are created with the case that the client passes, and only accessible using this same case. This will speed very large directory access, but some Windows applications may not function properly with this setting. For example, if "MyFile" is created but a Windows app attempts to open "MYFILE" (which is permitted in Windows), it will not be found.

A value of Forced lower is special: the case of all incoming client filenames, not just new filenames, will be set to lower-case. In other words, no matter what mixed case name is created on the Windows side, it will be stored and accessed in all lower-case. This ensures all Windows apps will properly find any file regardless of case, but case will not be preserved in folder listings. Note this setting should only be configured for new shares.

Here is the results comparing User Share vs DiskShare + Direct IO:

Have no idea what does it mean...

I just started with unRAID. I am on the latest stable which is 6.8.3. Today I will test SMB on cache disk bypassing unRAID file system.

Hi guys, unfortunately I see the same issue with SMB. Here is my results comparing Performance and On Demand CPU profile. Pstates are disabled in config, while running my CPU at max frequency even in idle.

 

Here is write speeds once again:

 

 

Currently, this prevents me to switch to unRAID in production. Shouldn't it be the high priority issue?
