[debian-users:17590] number of squid children?
中野＠成蹊大です。 いつもお世話になっております。
slink なホストで squid を動かしはじめました。
ii squid 2.1.2-1
動作自体は快調なのですが、子プロセスがたくさん
起動するので、ちょっと不思議に思っています。
pstree してみますと、
init-+-RunCache---squid-+-10*[dnsserver]
| |-pinger
| `-squid---16*[squid]
[以下略]
のように 16 個の children が立ち上がります。
# dnsserver の 10 個は squid.conf で指定しています。
それぞれの squid が結構なメモリを食うので、17 個
あると馬鹿にならない消費量になります。
proxy 143 0.1 15.0 10656 7156 ? S 18:16 0:05 squid -D -sNY
一方 slack 上で自分でコンパイルした squid ですと、
init-+-RunCache---squid-+-5*[dnsserver]
| `-unlinkd
[以下略]
のように、特に子プロセスは発生しません。 両者の
squid.conf の diff を取って (末尾に添付) 比べて
みたのですが、特に子プロセスの数を指定する部分は
ないようです。
slink の squid ですと、このような状況は普通なので
しょうか？ お使いの方からのコメントがいただければ
幸いです。
