Optimizing HDD performance on an openSUSE Leap 16.0 file server

English Install/Boot/Login

I’m running a file server on openSUSE Leap 16.0 and primarily use SMB and NFS for file sharing. My setup consists of an SSD for the OS and several HDDs for data storage.

I’m looking for ways to optimize the HDD performance. Specifically, I’m wondering if I can improve speeds by increasing the cache or tweaking other system parameters.

Does anyone have recommendations for sysctl settings, mount options, or caching tools?

You provide no information at all about the system that has the disks (“several HDDs”). Like partitioning/md-raids/LVM, file system types, present mount options, etc., etc.
