August 9, 20232 yr Seems like my copies start really quick when copying via windows after about 2 gigs I'm back to the standard drive speeds. Is that about normal? Is there any way to improve this further? I've love to be able to get at least 4gigs before the speed comes down. The weird thing when I first got the thing I ran a test and could swear it copied like 9 gigs at full speed. Edited August 9, 20232 yr by Aloyloy
August 9, 20232 yr Community Expert It will mostly depend on the device used and the amount of RAM, you can increase RAM cache percentage, but that usually makes performance worse for sustained writes, so only good if you write mostly in short bursts.
August 10, 20232 yr Author Oh well then, I guess no reason to bother upgrading my network then if the enhanced performance is only going to last a few seconds.

There are NVMe drives that can sustain high speeds indefinitely and plenty that can handle four gigabyte. What size and model do you have?
August 10, 20232 yr Community Expert A good NVMe device can sustain 1GB/s+ writes, but not the entry level ones.

But after a bit it's down to basically regular hard drive speeds. The weird thing is the day I got the thing I did a big giant copy of like 12 gigs and it handled it like a champ but now its down to slow after about 2 gigs tops.

August 17, 20232 yr Community Expert Are you trimming it regularly? You can also do a full device trim with blkdiscard to see if it gets any better (all data would be deleted), if still the same try a different device if possible.

But I did accidentally fill it because I had it configured wrong. I'll figure out how to trim and and give it another no now that the other cache issue is resolved.

Cleared it off of all status on it as much as possible with mover. Ran trim. Rebooted the server even. Waited a bit and copied a large file. After about 1.5ish gigs it falls back to normal hard drive speeds. Drive is a SK hynix Gold P31 1TB. I thought it would be able to keep up better then that.
August 24, 20232 yr Community Expert It should, but by the description still looks live a device problem, try with a different one if possible.
