[squid-users] Slow performance through Squid

Hi,

for personal use I've a Soekris net4801 board with OpenBSD and Squid
as firewall and proxy server.
Squid works in transparent mode on the same Soekris board, pf send to
it http traffic with an rdr rule:

rdr pass inet proto tcp from $prv_ad to any port 80 \
        -> 127.0.0.1 port 3128

Without rdr rule (so without Squid), Speedtest reports 3.5Mbps as
download speed, when I enable rdr speed goes down to only 2.6Mbps.
How can I improve my Squid config to reach 3.5Mbps?!

More details:
board: Soekris net4801
os: OpenBSD 4.6
squid: squid-2.7.STABLE6

- squid config: -------------------------------------------------
