[NTG-context] Super slow installation

[NTG-context] Super slow installation

[Thangalin via ntg-context]

Hi,

Installation of a fresh copy of LMTX has gone from a few minutes to
about 30 minutes. Here's what I ran:

1. Open terminal
2. Change to root
3. cd /opt
4. mkdir context-2023-05-29
5. cd context-2023-05-29
6. wget "http://lmtx.pragma-ade.com/install-lmtx//texmf.zip"
7. unzip texmf.zip
8. chmod +x install.sh
9. ./install.sh

mtx-install     | unzipping 'texmf-context.zip'
 518 files of 5180 done,   81058499 bytes, 0.403 seconds
 ... snip ...
5180 files of 5180 done,  171691491 bytes, 1.035 seconds
mtx-install     | installing tex/texmf-context, 4924 files
mtx-install     | new      :   0 % :     2447 :
tex/texmf-context/context-readme.txt
... snip ...
mtx-install     | new      :  48 % :    21898 :
tex/texmf-context/doc/context/sources/general/manuals/about/still-expanding-10.png

Getting to this point has taken shy of 15 minutes.

Any ideas what's going on or how to fix it?

Note that upgrading against the version prior to 2023.05.29 (i.e.,
without re-installing from scratch), the process happens pretty
quickly.

Thank you!

Still sluggish. Downloading texmf.zip took 22s for 50MB:

In the past, downloading 50MB has been much faster.

The following takes about 4 minutes:

Previously, getting to 22% was also quite quick.

Couldn't it be something on your side, like a misconfigured router or ad 
blocker or something? I get faster download times:

wget http://lmtx.pragma-ade.com/install-lmtx//texmf.zip

Here's the result from downloading a YouTube video using yt-dlp:

[download] 100% of  225.74MiB in 00:00:09 at 24.43MiB/s

9 seconds for 225 MB.

I haven't touched my router configuration in years.

https://www.speedtest.net/result/14802746497

Download 935 Mbps; Upload 106 MBps.

Looks fine on my side?

Re: [NTG-context] Super slow installation

FWIW, I'm seeing the same slow down issue from three different machines:

   1. My personal computer in Vancouver BC.
   2. A work computer on Vancouver Island (Victoria BC)
   3. Microsoft ADO servers (presumably in Seattle WA).

Is it possible there's a slow pipe from North America to Europe?

Could be. For me (Montreal, Canada) it took more than a minute:

This timeout is almost certainly because the last server has been set to ignore UDP traffic.

  $ traceroute -I lmtx.pragma-ade.com

uses TCP packets rather than UDP and we get the final response much more quickly, which is:

17  d57d1da5.static.ziggozakelijk.nl (213.125.29.165)
which is in Hasselt. :-)

> 
> Something is funky on the network.

Yes. A bit of weirdness in Canada - which could be down to a fault causing re-routing. But the Warsaw hop, with its huge increase in latency looks like a misconfiguration.

Update: just tried it through a VPN that emerges in Vancouver and I also get the trip to Warsaw with a big increase in latency. For some reason Aorta.net routing some (or maybe all) traffic through Warsaw - perhaps that's where the NSA pay them to spy on on all US->Europe traffic? [1]

[1] Joke. (Besides, they'd never do it for traceroute packets because they'd want to hide their snooping.) ;-)  [2]
[2] Also a joke ;-)

Re: [NTG-context] Super slow installation

[Thangalin via ntg-context]

[-- Attachment #1.1: Type: text/plain, Size: 598 bytes --]

From twelve99.net:


If you’re interested in our IP city prefixes, we have a lookup table on our
website: https://www.arelion.com/our-network/bgp-routing/bgp-communities
Scroll down to “Origin + Communities” and expand that section. You can see
that sea-b1 (your hop 8) is not in Brussels, but is our router in Seattle.



My guess would be that the hostname “us-was” for Liberty Global (aorta.net)
stands for U.S.A. and Washington D.C, not Warsaw. They’re probably using
ICMP tunneling for their MPLS backbone, that’s why the ping times are weird
for you.


Cheers!

Re: [NTG-context] Super slow installation

Hi all,

I think that this is all resolved now, but if not, maybe this extra info
will help?

I'm using this script to test:

   #!/bin/sh
   
   for x in \
       "https://speed.cloudflare.com/__down?bytes=$(echo '50*1024^2' | bc)" \
       "https://speedtest1.mnd.bulk.iss.as9143.net:8080/random5000x5000.jpg" \
       "http://lmtx.pragma-ade.com/install-lmtx/texmf.zip" \
   ;do
       echo "$x"
       curl -w 'scale=2;%{speed_download}*8/1024^2\n' -sSo /dev/null "$x" | bc
       echo
   done
   
Cloudflare should have a fast data centre near anywhere, and
...as9143.net is hosted directly by the ISP that lmtx.pragma-ade.com
uses. I'll also run 

   traceroute -I lmtx.pragma-ade.com

Good point about the MPLS.

I was using https://www.geolocation.com/ to do the geolocation and it claims Warsaw but that - in hindsight - is wrong. So "us-was" is likely to be Washington as per the name and is also the device "taking the blame" for the entirety of the MPLS latency. Since that will include the transatlantic time the extra 75ms isn't quite so bad as it looks.

i restarted the modems, switches, routers, virtual host and virtual 
machines .. that's all i can do, ok, i also updated the zips

the lmtx web server is a opensuse vm on a proxmox server on xeon driven 
hardware; the router is a fast pfsense (with failover) and the 
connection used is guaranteed 300/40 cable connection (i can't provide a 
fallback on the reasonable fast dsl line because that one as only one ip 
address that is used for something else http(s)

so it must be some hickup in the chain outside

Re: [NTG-context] Super slow installation

mkdir /tmp/context
cd /tmp/context
wget "lmtx.pragma-ade.com/install-lmtx/context-linux-64.zip"
unzip context-linux-64.zip
sh install.sh

Installation went quite quickly (after downloading the zip files). Ran it
cleanly twice.

Looks like it's back to its previous speed, thank you.
