G3ZSTD - Zstandard Compression Test

This page demonstrates the G3ZSTD native object using Zstandard (zstd) compression with configurable levels.

Test 1: Basic Text Compression with Different Levels

Original Text:

The quick brown fox jumps over the lazy dog. Zstandard is a real-time compression algorithm providing high compression ratios. It offers a trade-off between compression ratio and speed.

Original Size: 185 bytes

Level	Compressed Size	Ratio	Status
3	138 bytes	74,59%	✓
11	139 bytes	75,14%	✓
22	139 bytes	75,14%	✓

Test 2: Decompression Roundtrip

Original:

This is a test string for zstd compression. It contains repeated patterns: test test test and string string string and compression compression compression.

Compressed Size: 94 bytes

Decompressed:

This is a test string for zstd compression. It contains repeated patterns: test test test and string string string and compression compression compression.

✓ Roundtrip successful!

Test 3: Byte Array Compression

Original Array Size: 200 bytes

Compressed Size (Level 15): 213 bytes

Decompressed Size: 200 bytes

✓ Byte array roundtrip successful!

Test 4: Batch Compression of Multiple Items

Batch compressing 5 items at level 12:

Compressed Items: 5

Decompressed Items:

Item 1: First batch item for compression
Item 2: Second batch item with data
Item 3: Third item in the compression batch
Item 4: Fourth and final batch item
Item 5: Extra item to complete the set

Test 5: File Compression

Original File Size: 52 bytes

Compressed File Size: 23 bytes

Compression Ratio: 44,23%

✓ File compression successful!

Compression Level Guide

G3ZSTD supports compression levels from -5 to 22:

Range	Description	Use Case
-5 to 1	Very Fast	Real-time applications, streaming
2 to 8	Fast	General purpose compression
9 to 15	Balanced (default 11)	Good balance of speed and ratio
16 to 22	Maximum Compression	Archive, long-term storage
