[SOLVED] Slow loading of Internet webpages
Have a strange problem that started yesterday. Never had this problem before.
When I visit any website, the pages don't start loading right away, and then they load much slower than usual.
When I click on links or bookmarks, the browser hesitates, then slowly loads a little bit of the top of the page, then eventually the rest comes in.
Seems like something is interfering with the i/o.
It's not a hardware problem because my Win7 installation on the same PC, using Firefox and the exact same hardware, is performing as usual.
Other PCs on the network (wired and wireless) are running normally too. Not an ISP problem.
I tried it with my virtualbox xp and the same problem existed there.
Resetting the modem, router, machine had no effect.
Did a system update today (a day after the problem started) - no change.
Tried running Firefox in safe mode. No change. Cleared cache, etc. No difference.

Re: [SOLVED] Slow loading of Internet webpages
You've tried a different browser? (eg, Chromium)

Yes. Same thing with chromium. It's not the browser. It's something else.
FYI, I am not using a firewall either.
Something is delaying/interfering with the packets and it isn't the router/modem.

Re: [SOLVED] Slow loading of Internet webpages
Update.
I had a month-old version of my Arch installation on a USB which I use as a portable Arch USB Live. I booted that on a different PC that works fine with FF and WinXP, and the same slow load problem is taking place. I tried it with chromium too - same problem. This proves 1) That it isn't the hardware in my main PC (ethernet controller, etc), and 2) the problem began more than a month ago and I just didn't realize it because I wasn't on the computer much during the past two months. It isn't browser-specific. It's something specific to my Arch system.
Another thing: when downloading packages with pacman, I experience no speed degradation. Not sure what protocol pacman uses? Also, when I run speedtests on the web, the speed is correct.
Could it be possibly be Java-related? I ditched openjdk for oracle's java because recent versions of icedtea-web weren't allowing me to use the Interactive Brokers platform. I had tried running FF in safe mode, figuring if it was java or flash, that that would prove it, but the problem was the same in safe mode.
When I go to a site, FF will show "connecting" on the tab and the circle spins for a while. Once it seems that the connection is established, most of the page will load relatively quickly. MAkes me think it might be DNS related?
I'd like to re-install certain packages, but I do not know which packages are involved in the chain and which to re-install first.

Re: [SOLVED] Slow loading of Internet webpages
I went into the router's settings and enabled ipV6 according to videotron's instructions.
I rebooted and networkmanager is showing an ip address for ipv6.
The websites/webpages are loading at normal speed now.
I wouldn't call the problem "solved", but by enabling ipv6, it's somehow getting around it. Good enough. I'd love to know WHY and what the problem is.

Re: [SOLVED] Slow loading of Internet webpages
I solved this by changing the DNS IP addresses in /etc/resolv.conf.
Networkmanager overwrites that file, so I changed the connection's settings in networkmanager to Automatic DHCP (addresses only) and entered the OpenDNS servers manually. If you leave it at the automatic dhcp setting, it'll grab the what the router tells it to, and put it at the top of the resolv.conf file, thus defeating the go-around.
The websites are all loading at the proper speed now. I have no idea why 192.168.0.1 (i.e. via the router), after having worked for so many years, starting causing the delays. Weird.
