Just tried #1027 with the same results. Here is a debug log: https://www.dropbox.com/s/nlm8d7ggk0ltt4...7.log?dl=0 Oh yeah, those are smb:// shares. Tried to remove all of them just in case, and added back again.

smb:// uses the Samba library so shouldn't be significantly affected by the kernel, and certainly not any kernel CIFS changes.

You can try bisecting the 4.19-rc releases: https://github.com/LibreELEC/LibreELEC.tv/pull/2937

There were eight 4.19-rc releases, so try 4.19-rc1 and see if that has the same smb:// issue - if not, continue with 4.19-rc2 etc. The only difference between the rc releases and the matching 4.18.y build is the kernel (plus some updated Realtek drivers). If none of the rc releases have the smb:// performance issue then we can probably rule out the kernel, although I don't see anything else in #1023 which might be responsible for smb:// performance issues.

Are you using wired or wifi? If it's Wifi, are you sure it's not a new neighbour etc. knackering your Wifi performance? Measure your Wifi performance. Are you using a Realtek driver, if so maybe the changes for 4.19 need some tweaking.

I use these builds on i5 Skylake NUC with 5GHz wifi and Revo 3700 with wired 1GBps Ethernet, and I've tested smb:// to Windows 7 (SMB3) and I'm not seeing any performance degradation since #1023.
