One thing you haven't mentioned (as far as I can see) is the actual hardware
specifications of the machines?

Subject: [SLE] Linux still surfs slower than Windows


I have two Suse 9.1 Linuxes and one Win2k on a LAN behind a Linksys
WRT54G router connected to SBC/Yahoo DSL. The router gets a dynamic IP
via DHCP, and connects via PPPoE. It also receives DNS server
addresses. The LAN hosts have static IPs on subnet and
statically configured DNS server addresses set to the values shown by
the router. These DNS addresses are always the same:
and .

The Windows host also has a static IP and manually configured DNS
servers. Also, there is a Win2k VMware machine on each Linux box with
bridged networking and static IP and DNS configurations.

So a total of two Linux boxes, one real Win2k, and two virtual Win2k.

The problem is simply that the Linux boxes using Mozilla or Konqueror
web browsers, surf the web ridiculously slow. Typically 45 seconds to
load a page like, and 10-15 seconds to load simpler pages

The Win2k, both the real and virtual machines, all surf at instantaneous
speed using either Mozilla or IE.

I changed the Linux DNS server configurations to free servers: and, which improved speed significantly. Now
Linux surfs about 3-4 times slower than Windows on average for all web
sites. A big improvement, but still unacceptable. Typical 6-8 second
loads for, vs. 2-3 seconds for Windows.

I posted before "Terrible Web Surfing Speed" and will summarize the
results of the suggestions and other attempts at fixing this:

1. The only suggestion which improved matters was to use in the file

options timeout:1

This improved the surfing speed using SBC/Yahoo DNS servers to about the
same speed as using the free servers, still about 3-4 times slower than
Win2k. This is the condition I am in at this time.

2. Switching to DHCP IP and DNS assignments for the LAN clients did not

3. Turning off IPv6 did not help.

4. Captain Dondo suggested: "Well, perhaps your router/ISP is issuing
ICMP redirects and your linux box ain't set up to accept them? I don't
know if Windows accepts redirects by default; it makes it easier for the
user but opens up security holes.... Hmmm. Which way would Windows
lean? As root, run this command:
for f in /proc/sys/net/ipv4/conf/*/accept_redirects; do echo 1 > $f; done

Well I have all these already set to 1 so that can't be the problem:

> for f in /proc/sys/net/ipv4/conf/*/accept_redirects; do cat $f; done

5. Use the WRT54G as the DNS server. I tried this, and it works. Some
performance is a little bit better than either the free servers or the
options timeout:1, but still about 2 times slower than Windows.


Very close, but still disappointingly slower than Windows. It seems
with the router as DNS, that initial loads of new pages are slow, but
then loading again is very fast. Before, it was the same slow speed all
the time. But Windows still manages twice the initial load speed for
all pages.

Any further suggestions how to improve things would be appreciated.

Good day!
