NAS transfer speeds mystery....
Posted: September 3rd, 2020, 2:31 pm
A few weeks ago transfer speeds from my PC to my NAS (a Buffalo LS220) doubled from what they'd always been before, and have since dropped back, and I can't figure out why either happened.
I've had the LS220 for a couple of years now and always had transfer speeds to it from my PC of around 30-33MB/s. (A bit disappointing, but I'd always figured, hey, it's a cheaper end of the market NAS, so ok...).
I use it for general LAN storage and for backups and those are the figures I usually get copying files to it and also the speeds typically reported by Macrium.
That was up until a Friday three weeks ago when the Macrium logs show transfer speeds for that day and the following two days backups of 66MB/s, 64MB/s & 56MB/s, and when I noticed that in the logs on Sunday and tried copying files to the NAS I also got similarly high speeds.
Then the Monday and Tuesday it went back to the low 30s, both for copying files and Macrium, and then Wednesday it went back up to the 60s, only to drop back to the 30s a couple of days later, which is how it's been since, and I can't figure out why or, now that I know the setup is capable of better speeds, what I need to do to get those back, and keep them.
As far as I know, nothing changed over the period or leading up to it. The LS220 was on the same version of its software it had been on for ages, there weren't any Windows updates during the period, and I'd not changed anything, software, hardware or configuration, nothing at all.
So, the question is, what could be the cause of the change in transfer speeds, and, hence, what can I do to get and keep it high?
My setup is it's an LS220D0202 and it and my Win10Pro PC are connected to a gigabit switch. The LS220 runs continuously but the PC gets powered up & booted every morning and shut down & powered off every evening, and I have fast startup turned off, so it's always a from-scratch reboot. I have jumbo frames enabled all round, and at the times in question there is (and always has been) little/no other activity on the LAN.
Any one have any ideas?
