Hi, we use squid as shipped with SuSE Linux Enterprise 9 (squid-2.5.STABLE5-42.41).
The throughput is slower, when I get the data from cache and is faster, when I use the -r option to get the data from the webserver. --snip-- squid06:~ # time squidclient -p 8080 -r http://mueller.datevnet.de/Richter.pdf >/dev/null real 0m0.702s user 0m0.004s sys 0m0.015s squid06:~ # time squidclient -p 8080 http://mueller.datevnet.de/Richter.pdf >/dev/null real 0m6.085s user 0m0.001s sys 0m0.002s squid06:~ # time squidclient -p 8080 -r http://mueller.datevnet.de/Richter.pdf >/dev/null real 0m0.881s user 0m0.003s sys 0m0.012s squid06:~ # time squidclient -p 8080 http://mueller.datevnet.de/Richter.pdf >/dev/null real 0m5.785s user 0m0.001s sys 0m0.003s squid06:~ # time squidclient -p 8080 -r http://mueller.datevnet.de/Richter.pdf >/dev/null real 0m0.742s user 0m0.005s sys 0m0.012s squid06:~ # time squidclient -p 8080 http://mueller.datevnet.de/Richter.pdf >/dev/null real 0m5.890s user 0m0.001s sys 0m0.002s squid06:~ # --snip-- here the logfile entries: --snip-- 1153747089.142 698 127.0.0.1 TCP_CLIENT_REFRESH_MISS/200 2274238 GET http://mueller.datevnet.de/Richter.pdf - FIRST_UP_PARENT/127.0.0.1 application/pdf 1153747098.419 6081 127.0.0.1 TCP_HIT/200 2274245 GET http://mueller.datevnet.de/Richter.pdf - NONE/- application/pdf 1153747102.320 878 127.0.0.1 TCP_CLIENT_REFRESH_MISS/200 2274238 GET http://mueller.datevnet.de/Richter.pdf - FIRST_UP_PARENT/127.0.0.1 application/pdf 1153747109.546 5782 127.0.0.1 TCP_HIT/200 2274245 GET http://mueller.datevnet.de/Richter.pdf - NONE/- application/pdf 1153747111.639 739 127.0.0.1 TCP_CLIENT_REFRESH_MISS/200 2274238 GET http://mueller.datevnet.de/Richter.pdf - FIRST_UP_PARENT/127.0.0.1 application/pdf 1153747118.797 5887 127.0.0.1 TCP_HIT/200 2274245 GET http://mueller.datevnet.de/Richter.pdf - NONE/- application/pdf --snip-- This is my squid.conf --snip-- squid06:~ # grep -v "^#" /etc/squid/squid.conf | grep -v "^$" http_port 10.252.104.20:8080 http_port 10.252.104.80:8080 http_port 127.0.0.1:8080 icp_port 0 cache_peer 127.0.0.1 parent 8280 0 no-query no-digest no-netdb-exchange hierarchy_stoplist cgi-bin ?
