[SC.LUG] Mandrake 10.1 incredibly slow browsing on a small number of sites

[Robert Marshall]

Apologies to those who follow alt.os.linux.mandrake but we seem to have
run out of ideas there and I've still got the problem So as a late
Christmas brain teaser I present the following!

I upgraded to mdk 10.1 (community and then installed lots of updated
packages) at the beginning of December.  I'm finding that some pages load
almost unbelievably slowly for instance

http://www.cclonline.com/termsconditions.asp

takes 15 minutes to appear - I've tried a number of browsers and
they're the same.

http://www.computerpeople.co.uk/content_static/home.asp

is another culprit. They're both asp's but I'm seeing some AS pages
download fine. I've googled in vain and I've booted MandrakeMove which
doesn't have this problem, so I assume it's something I've done - or
failed to do! I'm running squid but wouldn't a problem there slow
everything down? I've stopped squid and the associated proxy firewall
rules and there's still no improvement
 
/etc/hosts looks ok as does /etc/resolv.conf

traceroute looks ok, ipv6 is disabled (reputedly a cause of slowness)

I ran strace with wget and each read appears to take about 5 seconds. 

  0.000059 select(4, [3], NULL, NULL, {900, 0}) = 1 (in [3], left {895, 286000})
  4.743655 read(3, "\r\n      </tr>\r\n      <tr>\r\n     "..., 16384) = 232
  0.040045 write(4, "\r\n      </tr>\r\n      <tr>\r\n     "..., 232) = 232
  0.044950 gettimeofday({1103754737, 511467}, NULL) = 0
  0.049571 select(4, [3], NULL, NULL, {900, 0}) = 1 (in [3], left {895, 142000})
  4.856806 read(3, "      <td>&nbsp;</td>\r\n        <"..., 16384) = 232
  0.000090 write(4, "      <td>&nbsp;</td>\r\n        <"..., 232) = 232


As the same machine worked ok with 9.2 (my 10.1 was a fresh installation
so I can still boot that) and MandrakeMove - running off a cd is also
fine. I'm completed bemused and would welcome any helpful brainwaves!
Any other avenues I could explore? I have two eth cards but still have the
problem when I take down eth1. Note that 99% of sites work fine, its just
a very few that are unusable
