I'm wondering what I can do to improve performance, or at the very least tell Unraid to utilise RAM as cache more freely. I'm permanently at 20-23% RAM usage (as a result of Windows 10 VM that i'm running), but otherwise the remainder of the RAM is not utilised in any way and sits dormant. However, if you are building a system with recent components, you might not even be able to find any compatible 2 GB sticks of RAM. I have noted that over the last day my RAM is barely ever used. When not using Unraid as an application server or virtualization host, the RAM is solely used to load the Unraid operating system from the USB drive at boot. Parity has since completed with no errors. During initial setup my parity drive was delivering 150-200MB/s write speed.
The new server has 64GB of ECC RAM, 256GB cache drive, and all drives are connected to a PERC H310 running in IT / pass through mode. Here is the copy from my server to Unraid: I have test copied from the source directly to my own computer and can confirm that it can deliver at least 100MB/s sustained. I'm currently in the process of migrating approx 10TB of data from my old server to my Unraid server however I have noted that the sustained transfer speed seems to get progressively slower over the duration of the copy, starting at 150-200MB/s, and slowly going down to 50MB/s, then settling around 20-35MB/s. Very new to Unraid, currently into my 2nd day of the trial and I've decided i'll be buying the pro tier and migrating my current Dell server.
