I have just switched one of my server installs of Resilio-Sync from Centos 8 (Stream) to Ubuntu LTS 20.01 and have noticed that the Web GUI is significantly slower, links once clicked don't always work (have to click again or refresh the page) - I have to regularly refresh the page.
The install is running on a Hyper-V VM running 8GB RAM and plenty of processor power. I also have installs on Windows and a Raspberry PI 4 all using the Web GUI which I can compare side by side on my local network and can see a real difference between the installs (the Windows and PI installs are far snappier).
I don't think this is Hyper-V as this was not something I encountered on CentOS.
Anyone seen this before?
Update
Solved - Issue was my own fault, in essence moved the root volume at the same time from an SSD to a RAID 01 HDD which was also dealing with syncing a TiB of data. Moved the root disk back to an SSD and issue resolved.
