KAEZlib压缩库测试

用户安装zlib库（KAE1.0）或KAEZlib（KAE2.0）后，可以通过本节提供的操作步骤测试压缩库功能和性能。

测试步骤需要在源码目录下操作。若KAE是通过RPM包或者DEB包方式安装，则在执行测试之前需要下载并解压KAE源码。

  1. 进入KAE源码目录中的测试目录。

    • KAE1.0：
      1
      cd kae_zip_engine/test/
    • KAE2.0：
      1
      cd KAEZlib/test/gtest/

  2. 测试KAEZlib加速库功能。

4
    mkdir build && cd build
cmake ..
make
./zlib_functest --gtest_filter=*Case*

    回显信息中SmallCase与LargeCase两个用例的执行结果均为passed，则KAEZlib加速库功能正常。

  3. 测试性能。

    1. 设置环境变量LD_LIBRARY_PATH并启用KAEZlib加速库。
      1
      export LD_LIBRARY_PATH=/usr/local/kaezip/lib:$ LD_LIBRARY_PATH
    2. 进入性能测试目录。
      • KAE1.0：
        1
        cd kae_zip_engine/test
      • KAE2.0：
        1
        cd KAEZlib/test/perftest
    3. 编译性能测试工具。
      1
      make
    4. 测试压缩性能。
      • 使用原生zip测试压缩性能
        1
        ./zip_perf -m 8 -l 10240 -n 1000

        显示结果如下。

kaezip compress perf result:
     time used: 335108108 us, speed = 0.233 GB/s
      • 使用KAEzip测试压缩性能
        1
        ./kaezip_perf -m 8 -l 10240 -n 1000
        显示结果如下。

kaezip compress perf result:
     time used: 10631524 us, speed = 7.348 GB/s

      可以看到压缩速度从0.233GB/s提升到了7.348GB/s。

    5. 测试解压缩性能。
      • 使用原生zip测试解压缩性能
        1
        ./zip_perf -d -m 8 -f itemdata.zlib -n 1000

        显示结果如下。

      可以看到解压缩速度从1.482GB/s提升到了9.422GB/s。

      解压缩命令中的“itemdata.zlib”为已压缩的文件，可以通过在压缩命令中添加-o itemdata.zlib来指定。
