Testing the KAEZstd Library

After installing the KAEZstd library, you can test the library functions and performance based on the operations provided in this section.

1. Install KAEZstd. For details, see Installation Using Source Code.
2. Test the functions of the zstd compression library.

   1 2 3 4 5

   cd /KAE/KAEZstd/test/gtest mkdir build && cd build cmake .. make ./zstd_functest

3. Test the performance.
   • Benchmark the system's built-in ZSTD compression library.

     zstd -b3 /home/KAE/scripts/compressTestDataset/itemdata

     Command output:

     3#itemdata   :  7316868   ->  1977124 (x3.701),  201.7 MB/s, 845.0 MB/s

   • Benchmark the KAEZstd library.

     /usr/local/kaezstd/bin/zstd -b3 /home/KAE/scripts/compressTestDataset/itemdata

     Command output:

     3#itemdata   :  7316868   ->  2158294 (x3.390), 438.5 MB/s, 1233.2 MB/s

     As shown above, the compression speed increases from 201.7 MB/s to 438.5 MB/s when using KAEZstd, demonstrating a clear performance improvement.
