Browsers are lagging when trying to load some webpages

rated 0 times [ 2] [ 0] / answers: 1 / hits: 365 / 1 Year ago, sat, september 10, 2022, 8:19:06

I'm facing a problem both on firefox (no addons) & Chrome (on Ubuntu 12.04).

Some sites like Facebook, Ask Ubuntu and Deviant Art are not loading even after 10-15 minutes. Other sites are running quite well (I can play YouTube videos, for example), so the problem seems to be webpage-specific.

What can I do about this?

When random sites are working while others are not I always check for MTU issue (or PMTU discovery) first. I'd recommend trying this and see if that helps:

sudo iptables -t mangle -I OUTPUT -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
