RE: [squid-users] squid slow --- don't know why

Here are my results, measuring my speed to servers within my own country,
using an ADSL connection via LAN on two clients. These two clients are the
only two active on the LAN right now.

With squid: (Windows client)
1. 327 Kbps
2. 370 Kbps

Without squid: (Windows client)
1. 286 Kbps
2. 338 Kbps
3. 324 Kbps

Without squid: (Linux client)
1. 61 Kbps
2. 271 Kbps
3. 293 Kbps

With squid: (Linux client)
1. 289 Kbps
2. 291 Kbps
3. 296 Kbps

As you can see, with squid configuration, there should not be a slowdown to
your Internet access. Yours is quite drastic. There might be a configuration
problem: could you please post your squid.conf file? Use this command:
grep "^[a-z]" squid.conf > squid.conf.org
to remove comments.

Wow! I didn't know it was that bad. I ran each test twice. I didn't
know if you wantted all the stats, or just the speeds. Below are the
speeds:

Without the proxy -
482 Kbits (I have a T1, I was shocked. But that's not a squid issue)
499 Kbits

With the proxy -
98 Kbits
16 Kbits

I kept an eye on top while doing the tests with the proxy set, and squid
did not take anymore than 2% of the CPU. The load average is 0.04 right
now.

Anything else?
