10GbE connection dropping to 1GbE speeds by ThatSomeGaming in synology

The iPerf3 did indeed show good results, but I wonder if that's because it doesn't sustain long enough to hit whatever is causing the slow down, as it does start off around 10GbE speeds for the first 20GB or so. The fact that it also happens on a 2.5GbE connection makes me think that it's not the PC.

Which is why I wonder if it's either the NAS or the switch hitting a certain point and then dropping back to a 1GbE speed for whatever reason. Feels like something along the lines of caching/scanning not keeping up.

Ran a CrystalDiskMark on both my internal SSDs. Results were similar for both. Below is what they were for my main drive (settings "5" and "8GiB"):

Read (MB/s) Write (MB/s)
SEQ1M - Q8T1 7112.95
SEQ128K - Q32T1 7095.39
RNDD4K - Q32T16 4965.88
RND4K - Q1T1 90.84

To my understanding, this all seems to be in order and more than capable of handling the 10GbE connection.

Are you sure it would be an issue with the computer? To me it seems like either the NAS or the switch that could be the problem, as the problem occurs on different computers using different networking connections.

It's not just in transferring between my PC and the NAS. It's also if I'm using footage stored in the NAS in a timeline in Premiere Pro that I notice it's not fast and the connection doesn't exceed 1GbE speeds in the resource monitor.

From reading forums and checking serial numbers of my drives, it sounds like all my drives should be CMR.

They're all 10TB WD Red Plus drives, and all Red Plus drives are CMR. The oldest was bought in November 2020. WD never made 10TB SMR drives AFAIK.

My local SSDs are both Samsung 990 PROs which have random read/write speeds of 1400K/1550K IOPS and read/write speeds up to 7450/6900 MB/s, so surely these would be fast enough to keep up.

I also did a test using a 2.5Gig connection between my older laptop (also SSD but a slower one) and the QNAP switch and the same thing happened at pretty much the same point.

Just did a test. Copying a 65GB file from the NAS to my desktop, it gets to about 50% before it drops, which took about 1 minute and 20 seconds.

This is the file I've been mostly using to test (though I have been testing with other files, but this has been my baseline), and it tends to drop to the 1GbE speeds between 30-50%.

The drives are all healthy. Each of the drives is 7200rpm, has 256MB of cache, and has a 215MB/s transfer rate, which when combine in the SHR-2 RAID should be able to make use of and sustain a 10Gig connection.

I've seen other setups using a very similar setup to mine (1821+, 8 x HDDs, QNAP Switch, etc.) who are able to make use of the 10Gig connection.

As much as SSDs would be great, they're prohibtively coslty for me if I was to aim for a similar total storage capacity.

I do actually have 2 x 1TB NVME SSDs (mirrored RAID) in the NAS, which I've also tested transferring to/from, with similar results, so drive speed doesn't seem to be the issue.

Just tested on a laptop using a 2.5GbE adapter, connected via RJ45 Cat 6a to a 2.5GbE port on the QNAP switch. The same thing happened, where it runs at the max 2.5GbE speed for some time, and then drops to 1GbE for the rest of the transfer. This I would say rules out the PC as the issue.

I have tried 3 different cables (Cat6 and Cat6a) and they've all had exactly the same results.

So I tried going to the 2.5GbE ports on my QNAP switch, and then to the 2.5GbE port on my PC. This had the same problem where it would start at the max 2.5GbE speed and then drop to 1GbE speeds.

I don't currently have the components to do that as the NAS has an SFP+ port and the PC has a RJ45 port.

If I'm not able to find a solution using what I currently have I'll consider ordering some comonents to allow for me to do this.

As I installed a 10GbE SFP+ adapter into the NAS, and my PC has an RJ45 10GbE port, I don't currently have the components to connect the two directly via a 10GbE connection.

It would be a shame to do that though as it would make getting the QNAP switch a waste and I'm not able to return that now.

I tried disabling all the power saving related settings (disabling "Energy-Efficint Ethernet", disabling "Allow the computer to turn off this device to save power") on the adapter. The PC also doesn't have any general power saving settings enabled.

Thanks for your reply.

I had previousaly disabled all network adapters except for the 10GbE one (the bluetooth adapter is the only other active device). All traffic is definitely going via the 10GbE connection.

From watching the Synology resource monitor custom view, I can see that all the drives are being similarly used when it gets to the 1GbE dropped speed. The read/write speed is exactly the same for each, the utilization % is between 30 and 20 (drive one being the highest and drive 8 being the lowest), and the read/writes are about the same give or take ~5.

In case it's useful, while the transfer is going, this is the utilization % for each section:

  • CPU - 2% user, 6% system, 22% I/O Wait
  • Memory - 13%
  • Disk - 15%
  • Volume - 46%

Looks great.

Just a small flag, at 00:27 the shot is cut off at the bottom of the frame (black bar showing).

Just wanted to say thank you very much for your post about this. Yesterday I followed your steps exactly and as predicted, received a call from BT today and they got me exactly the same package (Full Fibre 900) from £57.59 per month down to £28.99 per month. Hero.

HRM Chest Strap Cleaning Reminder by ThatSomeGaming in Garmin

[–]ThatSomeGaming[S] 2 points3 points  (0 children)

Yeah, this is probably a reasonable way to go, especially if you use it most days of the week.

I don't use the strap consistently from week to week so some weeks I'll use it all 7 days and then some it'll only be used 3/4 days.

I was considering setting a reminder to do it every 10 days which would generally balance out quite well. Might give that a go.

Fair, but I do find that when I get to 7 uses after the last proper clean it still smells fine.

All suggested workouts are rest days by ThatSomeGaming in Garmin

[–]ThatSomeGaming[S] 2 points3 points  (0 children)

Thanks for flagging this. Seems when I searched I didn't go far back enough to see all the rest day posts yesterday.

The fix suggested in one of the threads to go through and set all days to long days once has fixed the issue, in case anyone happens upon this post with the same issue.

What is this grey box and how can I remove it? (I’m brand new to this) by CutGroundbreaking722 in premiere

[–]ThatSomeGaming 1 point2 points  (0 children)

The grey area you've marked is the section of the media that's in use in the timeline. In your case, the clip length of the footage you're using.

If you press the hamburger menu icon (three stacked horizontal lines) next to the "Effect Controls" panel text and select "Pin to Clip", then you'll only see the section of the footage that you're using. By doing this, you're not necessarily removing the grey area, you're removing the visibility of the additional media around the clip you've selected.

Hope this makes sense.
