Whetstone/Dhrystone综合基准测试
用gcc带参数-float-abi=softfp -O3编译全部代码
源码
测试代码在http://www.rowley.co.uk/arm/whet_dhry.zip.
备用地址http://freespace.virgin.net/roy.longbottom/benchnt.zip
编译/运行
?
结果
Dhrystone
Microseconds for one run through Dhrystone: 1.2 Dhrystones per Second: 809061.5
Whetstone Crippled
Loops: 1000, Iterations: 10, Duration: 24 sec. C Converted Double Precision Whetstones: 41.7 MIPS
用'gcc -mfpu -float-abi=softfp'重新编译Whetstone, 结果更好:
Loops: 1000, Iterations: 100, Duration: 106 sec. C Converted Double Precision Whetstones: 94.3 MIPS
上面的测试没有带-mfpu=vfp编译, 所以大部分运算时间都花费在SQRT方法上. 用了vfp后提升很大:
Loops: 1000, Iterations: 100, Duration: 15 sec. C Converted Double Precision Whetstones: 666.7 MIPS

路由
方法
- 一台带两个lan口的OpenBSD 5.2电脑在不同域用两个lan口直接连接树莓派.
- 在OpenBSD上的一个接口跑iperf -s, 另一个跑iperf -t 300 -c, 树莓派负责在中间路由.
- iperf v2.0.5.
- 测试150秒后树莓派系统负载.
