前言
之前进行了开发环境等的体验，现在对各方面的性能进行一个定性体验。
跑分
打开WSL终端
下载代码
git clone
cd coremark/
vi simple/core_portme.h
修改
#define COMPILER_FLAGS \
FLAGS_STR /* "Please put compiler flags here (e.g. -o3)" */
#endif
为
#define COMPILER_FLAGS \
"-O3" /* "Please put compiler flags here (e.g. -o3)" */
#endif
如果-O0编译则改为”-O0”
typedef ee_u32 ee_ptr_int;
改为
typedef unsigned long ee_ptr_int;
编译
export PATH=$PATH:~/lichee/out/sun8iw11p1/linux/common/buildroot/host/usr/bin
arm-linux-gnueabihf-gcc -o coremarko0 core_list_join.c core_main.c core_matrix.c core_state.c core_util.c simple/core_portme.c -DPERFORMANCE_RUN=1 -DITERATIONS=100000 -Isimple -I. -O0
arm-linux-gnueabihf-gcc -o coremarko3 core_list_join.c core_main.c core_matrix.c core_state.c core_util.c simple/core_portme.c -DPERFORMANCE_RUN=1 -DITERATIONS=100000 -Isimple -I. -O3
导入到windows下
cp coremarko0 coremarko3 /mnt/d
然后通过串口rz导入到开发板
添加可执行权限
chmod +x coremarko0 coremarko3
运行
./coremarko0
./coremarko3
结果如下,可以看到优化不同差距较大

RAM性能测试
WSL中
下载代码
git clone https://github.com/qinyunti/STREAM.git
cd STREAM/
编译
export PATH=$PATH:~/lichee/out/sun8iw11p1/linux/common/buildroot/host/usr/bin
arm-linux-gnueabihf-gcc -O3 -DSTREAM_ARRAY_SIZE=5000000 stream.c -o stream.5M
导出到windows下
cp stream.5M /mnt/d
然后通过串口rz导入到开发板
添加可执行权限
chmod +x stream.5M
运行
./stream.5M
结果如下
root@T3/A40i-Tronlong:~# ./stream.5M
-------------------------------------------------------------
STREAM version $Revision: 5.10 $
-------------------------------------------------------------
This system uses 8 bytes per array element.
-------------------------------------------------------------
Array size = 5000000 (elements), Offset = 0 (elements)
Memory per array = 38.1 MiB (= 0.0 GiB).
Total memory required = 114.4 MiB (= 0.1 GiB).
Each kernel will be executed 10 times.
The *best* time for each kernel (excluding the first iteration)
will be used to compute the reported bandwidth.
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 52219 microseconds.
(= 52219 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.

WSL中
下载代码
wget https://pyropus.ca./software/memtester/old-versions/memtester-4.5.1.tar.gz
tar -xvf memtester-4.5.1.tar.gz
cd memtester-4.5.1/
编译
export PATH=$PATH:~/lichee/out/sun8iw11p1/linux/common/buildroot/host/usr/bin
arm-linux-gnueabihf-gcc -O3 memtester.c tests.c -o memtester
导出到WINDOWS下,下载到开发板
cp memtester /mnt/d
chmod +x memtester
运行
./memtester
运行结果如下,默认一直测试下去,可以最后指定测试次数
比如
./memtester 128M 1
128M表示测试RAM大小
1表示测试一次
另外也可以-p直接指定物理地址,适合在板子开发阶段裸机代码直接指定物理地址测试。

速度和SD卡本身有关，也没有考虑缓存，所以结果仅作参考。
总结
以上综合对性能进行了测试,感觉性能还是非常不错的，各测试结果仅作参考，因为环境等因素不一样测得结果也会不一样，包括存储的测试方法也不是很科学，比如没有考虑缓存等。上述测试只是一个定性的性能体验，板子的性能是一个综合的体验，需要是面对真是的应用场景才有意义，并且针对场景优化也很重要。
