DNS: ストレスツール dnsperf , resperf

Fedora のパッケージに dnsperf ってのがあったので使ってみたー。

[root@arizona ~]# yum list | grep dnsperf
dnsperf.i586 @updates

resperf-report ってのを使うと結果をグラフ化してくれる~。

arizona ( 負荷ツール ) --- alaska ( , BIND 9.6.1-P1 )

[root@alaska ~]# named -v
BIND 9.6.1-P1-RedHat-9.6.1-4.P1.fc11

-s サーバ -d クエリリスト -m QPS最大値

-m 1000 = 1000qps まで負荷をあげていく

[root@arizona ~]# resperf-report -s -d queryfile-example-100thousand -m 1000
Done, report is in xxxx.html
[root@arizona ~]#

-- result
