[squid-users] 3.1.0.14 tproxy slow preformance

Hello,

I have compile squid 3.1.0.14 under both Ubuntu 9.04 and Fedora 11.
Both complete successfully and work fine until I enable tproxy then the
requests performance drops.

here is a httperf of squid without tproxy

httperf --client=0/1 --server=localhost --port=3128 --uri=/
--send-buffer=4096 --recv-buffer=16384 --num-conns=1 --num-calls=1
Maximum connect burst length: 0

Total: connections 1 requests 1 replies 1 test-duration 0.003 s

Connection rate: 316.1 conn/s (3.2 ms/conn, <=1 concurrent connections)
Connection time [ms]: min 3.2 avg 3.2 max 3.2 median 3.5 stddev 0.0
Connection time [ms]: connect 0.9
Connection length [replies/conn]: 1.000

Request rate: 316.1 req/s (3.2 ms/req)
Request size [B]: 62.0
