Whetstone/Dhrystone综合基准测试

用gcc带参数-float-abi=softfp -O3编译全部代码

编译/运行

?

结果

Dhrystone

Microseconds for one run through Dhrystone: 1.2Dhrystones 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

- Download source, compile as delivered
- Start game
- Runs at display's native res, in my case 1280x1024
- Bitdepth stuck at 16bpp, not sure how to change, values in q3config.cfg seem to be ignored
- In-game console commands:
\timedemo 1
\demo four

结果

armel "driver info" : http://i.imgur.com/wtYhB.jpg armel timedemo score: http://i.imgur.com/i2TkN.jpg 20.2fps
armhf "driver info" : http://i.imgur.com/8nqa1.jpg armhf timedemo score: http://i.imgur.com/dUu0g.jpg 28.5fps

IO

USB总线

  • 所有的IO都用同一个总线, 所以所有IO的总和不可能超过设计的60MB/s速度;
  • 高速USB盘的测试结果显示速度可达30 MB/s:
root@raspberrypi:~# dd if=/dev/sda of=/dev/null bs=32M count=10 iflag=direct
10+0 records in
10+0 records out
335544320 bytes (336 MB) copied, 10.6428 s, 31.5 MB/s

SD卡

这部分已经移到RPi_SD_cards#Performance

NIC(网卡)

编译/运行

局域网中:

iperf -s

树莓派中:

iperf -t 60 -c <SERVER_IP_ADDRESS> -d

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.
