bind和mydns性能比较

网络环境：机房局域网百兆共享下两台机器

机器配置：被测试机器(主) 双核 2.4GMZ，缓存2M 内存 1G scsi硬盘
                    测试机器(从)   双核 3.0GMZ，缓存1M 内存 1G scsi硬盘

软件环境：主dns装有两套软件bind 9.4.2 (源代码编译，数据存储用文本)和mydns（数据存储用mysql数据库）；运行一个相同的域并且记录也一模一样；禁用递归，此服务器用作权威dns只供客户查询域名。
测试软件：bind自带的queryperf
测试目的：bind和mydns性能比较
测试结果：
运行bind后，测试结果如下
[root@dns2 queryperf]# ./queryperf  -d ceshijilu1 -s 8.8.8.8 -l 50

从Queries per second参数来看，mydns的性能（29588.748989 ）要比bind（12509.437715）强很多，大约二倍。
测试过之后都想把现在用的bind服务器换成mydns。
