OK I decided to write this up after unsuccessfully being able to find all the required info I needed in one place. In this setup we will be using Ubuntu Server 22.04.2 LTS as the OS. I have this running on a home lab ESXi server 8, on a HP Compaq Pro 6300 SFF CPU = Intel Core i7-3770 Installed Memory 16 GB I have some 10K SAS drives installed for the VM's If you have not already, navigate to  Get Ubuntu Server | Download | Ubuntu and download the 22.04.2 LTS ISO Next Lets create our VM that we are going to run this in. *Note Im using ESXi however you can probably do this in Workstation, Fusion, VirtualBox etc The main things to note on the VM creation. Set Ubuntu 64 bit as the guest OS Set your CPU relevant to the physicals CPU, I will be starting with 4 VCPU Set your Memory to as much as you can tolerate, I will be using 12 Disk Space - we are creating a 100G swap file, and the rest of the file can take up some room , so more is better if you can afford it Dont forget to add the U...

Synology NAS performance issue after updating to DSM 7

-
Image
Looks like Synology had a significant oversight when they allowed customers of the DS416Play to upgrade to the latest DSM 7 OS. The default configuration comes with 1GB of memory, this was adequate for the version 6 DSM, however it appears the version 7 clearly has a larger memory footprint and does not leave enough room for file operations. In my case I purchased a 8GB stick of memory: https://www.amazon.com/G-Skill-Ripjaws-204-Pin-SO-DIMM-F3-1600C9S-8GRSL/dp/B00EOUFEG2 Or This one has been reported to work as well: https://www.amazon.com/Crucial-Single-PC3-12800-Unbuffered-204-Pin/dp/B006YG8X9Y Followed this YouTube tutorial on disassembling the NAS https://www.youtube.com/watch?v=zE6P7F16X7Q And booted back up. It now runs like it did previously and my backups function again. More info here.  https://community.synology.com/enu/forum/1/post/146281?page=1&reply=463033 I wish i would have taken a screen shot before the upgrade, but here is TOP after the upgrade:
