Hey,
I have a TrueNAS RC0 machine with 32GB ECC ram. It is generally working pretty great. I noticed something odd and I am wondering if it is a tuning issue.
The machine had two pools, an old one and new one I migrated data to. After migration, mostly for kicks and a little bit of testing, I used WinMerge to compare the contents on each pool. The test consists of checking the file names, dates, and randomly examining some data (quick comparison) for each file.
The test seemed to be going as fast as anyone could expect, running at a speed near 1Gb. What I experienced was if I went to any other file while the test was running, the response time was horrible. Clicking a video (even a short one) might take almost a minute to open when it used to be instantaneous.
I believe the issue is related to caching, as it took a while to go back to normal if I paused the test. Also, if I clicked around to different points in a video for a minute or two, the video I was working on would eventually become responsive even with the test running.
I know more memory is better, but I really expected 32GB to be plenty. I also have a M.2 drive I am not certain is being utilized at all for some kind of cache. Is there something I can adjust to help?
