Hi all,
I'm going crazy with squid configuration. I've been trying to make it
work
fine for couple of weeks and finally gave up. Please, help! :)
The problem is that squid responses are very very slow. I can notice a
significant delays even when I use squid by myself (only my browser
using
it) and if I let some more people use it as transparent proxy, there is
barely any response from squid on all machines.
I install squid on slackware 12.2. Already tried few versions
(2.7.STABLE5,2.7.STABLE6, 3.0.STABLE11) and many compile parameters.
Let's
say I do:
./configure \
--prefix=/usr \
--includedir=/usr/include \
--datadir=/usr/share \
--bindir=/usr/sbin \
--libexecdir=/usr/lib/squid \
--localstatedir=/var \
--sysconfdir=/etc/squid
I have the other instance of squid on other machine which works fine.
But
even when I move the config from this machine to my slackware box it
does
the same way - SLOW.
System configuration is:
# uname -a
Linux ninja 2.6.27.7-smp #2 SMP Thu Nov 20 22:32:43 CST 2008 i686

This is what I call SLOW:

Where was this request run from (the proxy itself, or another
computer)? Was this request intercepted by the proxy, and if so, how?
It was run from another computer. Intercepted by proxy.
The configuration is something like:
Internet
|
eth0 |
|-------------|
| Proxy Box |
| ninja |
|-------------|
eth1 |10.10.0.26
|
|
| 10.10.0.0/22 network
|
|
Client (10.10.1.4)
There is iptables rule at proxy box:
iptables -A PREROUTING -t nat -i eth1 -s 10.10.0.0/22 -p tcp --dport 80 -j
REDIRECT --to-port 3128
What does the access log look like after this request?
In access.log around this request there was :

Hmmm... I didn't find such a records in cache.log before ("no explicit
transparent proxy supported"). May be because I compiled squid with
"--enable-linux-netfilter" that time. Anyway it worked the same way then.
That message only occurs when interception support is DISABLED during
build and attempted to be used at run-time.
It's probably causing the forwarding loops, which are guaranteed speed
killers.
The alternative is that the site you are trying to contact is virtual
hosted. When asked for raw-IPs such as can be generated by a
non-intercept supporting squid when given intercepted requests.
