Solved Slow upload
-
I'm getting about 20Kb/sec uploading files. I tried a different SD card formatted at Fat32 64k as suggested in a post some months ago. that didn't help. Below is the M122 from right after the upload. My Duet sits 2 feet from my router.
Any recent development that may help here?

The SD card write time looks very slow. I suggest you get a new SD card, preferably a trusted brand, either class 4 or class 10. Format it with 64kb clusters if you can, or 32kb clusters if you can't.

You need to configure FileZilla to use only one connection when uploading files. It defaults to 2.

@dc42 The cards are Sandisk Ultra but without class indicator so probably old. I'll get a new one. Wish Duet would come with less inferior sd card. I will try the Filezilla setting as well. As soon as I have the cards I'll update. Thx!!
-
I would have expected Sandisk ones to work well, assuming they are genuine. But if they have no class indicator, that's very odd. Did they come from us, or somewhere else?
Last time I tested the cards supplied with the Duet, they worked well, upload speed was within about 20% of the top ones I tested. But perhaps we have changed supplier since then.
-
The card it came with was no brand 4GB class 4
-
I have the same unbranded 4GB card that came with Duet (this year) and it is fast.
A big file (5MB) starts at 700KB/sec and drops to 580KB/sec towards the end. That's fast enough for me, didn't bother to insert any of my other cards. -
@sigxcpu in that case I don't know what is going on. I did receive it this year; black micro SD Class 4 (C04G taiwan). I just tried speedsmart on my ipad connected to same wifi and got 16Mb upload speed.

Your iPad will be using a large cache, so it's measuring the WiFi speed not the SD card speed, unless you upload a truly huge file e.g. size at least 10x the amount of RAM in your iPad.
-
@dc42 Got it, it was more to check that my router wasn't crapping out. I have some class 10 cards coming my way and I'll will post any updates on any progress.

Hey, just chiming in to say I'm having the same issue all of a sudden (I've had my board for around half a year now and I believe this issue started a day or two ago).
Uploads are fine for an instant-- it says it's hovering around 3 - 5Mb/s-- but then immediately crashes down to around 60 Kib/s.
Uploading a 3 MB file took long enough for me to google other peoples' concerns in this forum, find no solutions, and then register an account and start typing up this reply before the file finished uploading.
I've already tried reformatting my SD card with 64k clusters but no success; same behavior as before.
Running M122 command immediately after upload gives the following data for my SD card:
"SD card 0 detected, interface speed: 20.0MBytes/sec
SD card longest block write time: 184.6ms"Any thoughts/suggestions?
-
-
Just uploaded a big file (15.6MB) and got this:
SD card longest block write time: 660.7ms, max retries 0
M39 reports:
SD card in slot 0: capacity 15.93Gb, free space 15.89Gb, speed 20.00MBytes/sec, cluster size 64kb
The upload hovered between 500 and 700 KB/sec. I am not sure that value is so relevant.
I've seen short stalls un upload, but then it resumed at the mentioned speed.
Maybe some cards have more stalls, so the total speed is reduced much more?
I need to mention that I've replaced original unbranded Duet card (4GB) with this one (SandDisk UHS something) after reading this topic and the old one was a little better. This one has a pause when it starts the upload then continues fine.
-
@sigxcpu said in Slow upload:
SD card longest block write time: 660.7ms, max retries 0
I haven't seen a block write time as long as that before. Does M122 show any SD card retries?
As SD cards get older, they reach the point at which some of the storage on the card has been written several times, and they start to do wear levelling. This involves copying blocks of data around and/or writing data multiple times. The result is that some write operations start to take much longer.
-
I just received my brand new SandDisk 32Gb UHS-I class 10, so here's my latest. It's not good news
Upload speed out of box: ~110KiB/s (not as slow as before but hardly impressive)

@core3d-tech Are you using a router that supports both 2.4Ghz and 5Ghz networks? If you can, try only enabling the 2.4Ghz network and test again.
Does the router have any traffic control functions enabled?
Can you disable IPv6 on the router and sending PC?
-
@phaedrux turned off 5Ghz, turned off Qos (only traffic control I'm aware of), turned off ipv6 both on asus as well as network sharing adapter settings. Upload speed still around ~100KiB/s. Did not seem to do the trick
-
I've been having slow uploads for some time.
The cure for it in my case was to rotate the printer 90 degrees.
2.4 mhz is quite sensitive to antenna orientation and position
-
Some development here. I just removed my current ASUS router (2 feet away) from the duet and added my NETGEAR router (on that is on the other side of the house, 1 wall, 1 ceiling, 50 feet away).
Upload tripled in speed running over 350KiB/s (still not 600 but much better). Clearly there's something it doesn't like about the ASUS setup.

The sub-optimal aerials on most routers ( so they look nice and neat ) tend to have blindspots in surprising places, multiple aerials can interact and make this worse when close by

Interesting, I am using an Asus DSL-AC68U router and I get 750 to 800kbyes/sec upload speed for a 10Mbyte file. WiFi signal strength is -51dBm.
