Slow Download Speed on fresh install

DarkCodeOrg · 2020-07-28 17:40:28

Hey there guys i got started with arch linux two days back and i dont know why from yesterday i am facing some problems in downloading anything from the browser.

I have tried using different browsers (firefox , chrome, chromium ) and all but no use, i tried updating my mirrors using reflector, changing my nameservers (have included opendns nameservers and googledns also) but all of them were useless, i tried searching over the web for solutions and found many but none of them worked (using networkmanager, using this command "sysctl net.ipv4.tcp_ecn=0" although i have no clue what it does, .
The awkward thing is this only happens when i try downloading from any browser, pacman downloading speeds and normal browsing speeds are fine and woring good , i generally get a 50 mbps download and 40 mbps upload but these download speeds have reduced to approximately 0.1 mbps, I also tried out internet speed test and it gave me good results (45 mbps down and 20 mbps up).

result of

 $ time wget https://www.google.se

Please reset the MTU to 1500, see https://nielshagoort.com/2016/05/03/jum … -involved/ for an explanation what that is.

The bottom line of your post is
* downloading w/ wget/curl: good
* browsing w/ any browser: good
* browser speed tests: good
* downloading w/ browser: bad
?

When you download files w/ the browser and set /dev/null as destination file (just type that into the path box of the save dialog), is the speed good or bad?

Okay so as seth told i reset the MTU size to 1500

i was trying to install the community version of burp suite but there google chrome does not let you specify the path manually, so i thought of using Wget but unfortunately burp's site doesnt let me copy the link address to their download file (.sh file) so i went with something else and tried out with alpine linux iso (130 mb)

command

wget http://dl-cdn.alpinelinux.org/alpine/v3.12/releases/x86_64/alpine-standard-3.12.0-x86_64.iso -O /dev/null

result:

the results were not bad as u can see above ,so i thought of giving burp suite another try but guess what , the download speed was again sluggish 0.1 mbps

so i would rate wget speed = good
browser download speed = bad

Since you suggested that

this only happens when i try downloading from any browser, pacman downloading speeds and normal

it's pretty important for this test to use the browser to download sth. into /dev/null
You can compare the wget download into /dev/null w/ a download into your $HOME though (to confirm the above)

You can configure chrome/chromium to ask where to save a file, chrome://settings/downloads

i had already set up chrome to ask the download path before downloading but while downloading it , i cannot "specify the path" or type in the path instead i have to select the folder graphically and so i tried going to /dev/ but there was no "null" dir as expected

and today i found something more disturbing i.e the download speed has gone down with wget also

i ran

 wget https://github.com/zaproxy/zaproxy/releases/download/v2.9.0/ZAP_2_9_0_unix.sh

to install owasp-zap under my home directory
and result was this

...

Saving to: ‘ZAP_2_9_0_unix.sh’
ZAP_2_9_0_unix.sh 1%[ ] 1.55M 9.43KB/s eta 2h 28m ^

but my pacman download speeds are still good like 8-10 mbps

and even trying to download owasp zap in /dev/null with wget returned pretty low speeds

wget https://github.com/zaproxy/zaproxy/releases/download/v2.9.0/ZAP_2_9_0_unix.sh -O /dev/null

...

Saving to: ‘/dev/null’
/dev/null 0%[ ] 152.57K 11.4KB/s eta 2h 25m

so i again tried downloading the alpine linux iso file under /dev/null and got a fair speed like 2-3 mbps

wget http://dl-cdn.alpinelinux.org/alpine/v3.12/releases/x86_64/alpine-standard-3.12.0-x86_64.iso -O /dev/null

and so tried downloading alpine linux iso from their website using my chrome browser
and you know what it just downloaded within seconds (i downloaded it in my home dir)
then i tried installing the arch iso from a mirror site and u know what i got a 4-5 mbps speed

WTF !! i was like staring at the screen and see the iso file download within 60 seconds

is the problem only with specific sites ?? since i dont think this is a browser related problem now
this spooky phenomenon is just overwhelming me
and i have still not found a way of directly downloading from browser to /dev/null

It would seem so.
There's also https://bbs.archlinux.org/viewtopic.php?pid=1916561 but that guy's from Brazil… (and by "google.se", you probably live on the other side of the atlantic?)

and i have still not found a way of directly downloading from browser to /dev/null

Just type "/dev/null" into the "name" box at the top of the dialog, but that should now be irrelevant - it's not the browser, you've just an unstable download speed.
