no problem

Asked by fred.kelsey

Just wanted to say thank you for the Ubuntu 10.04 operating system C.D.
It installed and works great.
Mozilla Firefox was very slow - but after altering url:config a bit, it now works fast.
Thanks again,
Fred Kelsey

You can also try installing dnsmasq and adding as your first nameserver

If you also run:

gksudo gedit /etc/sysctl.conf

add these lines to the bottom:

net.core.rmem_default = 524288
net.core.rmem_max = 524288
net.core.wmem_default = 524288
net.core.wmem_max = 524288
net.ipv4.tcp_wmem = 4096 87380 524288
net.ipv4.tcp_rmem = 4096 87380 524288
net.ipv4.tcp_mem = 524288 524288 524288
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1

Save the new file, if you also disable IPv6 (assuming you don't use it) you can get more speed:

gksudo gedit /etc/default/grub

find this line
and change it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"

Save the file and close gedit and run:

sudo update grub; sudo reboot

The web will now be a little faster, firefox isn't a quick browser but little tweaks can make it nice

try seamonkey or google chrome for speed...otherwise firefox is good for general usage and reduce the plugins or addons in firefox they take lot of time in processing the links clicked.
