Proxmox Updates are Downloading Slow

Lonnie · Mar 3, 2016

This last set of updates are downloading quite slow: between 10 to 25 KB/sec (taking over 20 minutes per server).

The slowness seems to be server-side, because the local connection is 50mb down and 10mb up, while nothing else on the internet is downloading slow.

Its not that big of a deal, but also who likes to wait 20 minutes for something that could take 1 minute.

I'm aware that you can change software download sources in debian, but I thought I'd ask here first to see what other admins are doing.

Please advise. Thanks.

Hi,

do you taking about http://download.proxmox.com ?

No, I'm talking the "Update" button on the tool bar (in Proxmox 4), the one that opens a console in a web-browser-window and you type 'y' to download the updates. That's what's slow.

Last few days I've noticed that the enterprise repo is very slow too. I'm seeing about 25-30Mbps with apt-get, causing the kernel downloads to take over 20-30 minutes.

We reboot the Server.

If you tell your location (e.g. your IP), others can check if its also slow for them.

Most times the issue is somewhere in the networks between our download servers and your network. If the issue is still there, please contact your ISP and we can also check this with our datacenter network.

I'm not even clear that it is Proxmox's fault. Could it just be the debian Jessie servers causing this?

Lonnie · Mar 5, 2016

Typically I can download 63 MB is less than a minute. Take a look at this:

The same problem here trying to update some servers in Chile:

Same issues. Getting ~21 kB/s. Traceroute from Washington state ends up in Germany. Are there 'closer' servers?

RobFantini · Mar 23, 2016

same slow speed here . the good thing is there are probably many more proxmox downloads

to get around the issue here we apt-get update one node then:

Code:

rsync --del -va     /var/cache/apt/archives/     TARGET:/var/cache/apt/archives/

RobFantini · Mar 23, 2016

another option is to use apt-cacher-ng . ( in the past it would not work with pve-enterprise . )

apt-cacher easy to set up in a lxc. it helps lessen traffic at the debian / pve repositories and you get extremely fast updates - assuming you've at least a few debian systems.

vkhera · Mar 23, 2016

Right now I'm getting about 40-50 kB/s download to east coast USA (just outside Washington DC).

dmox · Dec 14, 2018

Are there any problems at the moment? I am sitting near Frankfurt (ISP Telekom) and my download of the proxmox repo (non-subscription) is starving at 2 KB/s.

also here, in germany, two servers one near Kassel, one near Göttingen 2019-08-01:

I would like to get this back up.
Today I was annoyed by the repeaded 20kb/s download speeds on my PVE at home.
I wondered why on my PVEs in the Datacenters the download is fine but at home its awful. (I have a 100/40mbit connection)

From what i can compare between two nodes ist the following:

I guess there is something weird going on with the cdn...

I changed download.proxmox.com to de.cdn.proxmox.com in my apt sources and now the download is at my maximum possible speed.

seems like your home IP is geo-resolved to outside of the EU, and thus directed to our mirror node in Canada..

robingr · Oct 18, 2019

I have doublechecked that, both IPv4 and IPv6 are resolved to be german DTAG IPs.

I didn't mean to imply that the fault is on your end. it's likely a wrong/outdated geoip database entry.

robingr · Oct 18, 2019

You maybe could check the logfiles of the canadian webserver for some random DTAG subnet, I assume that I am not alone with this problem.

If you can point out that this is a common problem, I am sure the CDN provider can solve the issue.
