JAR vs LZ4
Perbandingan lengkap antara Java Archive dan LZ4 Compressed — ukuran file, kualitas, kompatibilitas, serta format mana yang sebaiknya dipilih untuk alur kerja Anda.
Java Archive
Archives & CompressedJAR is a ZIP-based archive for Java class files, metadata, and resources.
Tentang file JARLZ4 Compressed
Archives & CompressedLZ4 is an extremely fast lossless compression algorithm focused on speed over compression ratio. It can compress at over 500 MB/s per core and decompress at multiple GB/s, making it the standard choice for real-time and in-memory compression.
Tentang file LZ4Perbandingan Keunggulan
JAR Keunggulan
- Universal Java distribution since 1997.
- Self-contained: one file holds code, resources, and signatures.
- Executable via `java -jar` with zero setup beyond a JVM.
- Cryptographic signing for code provenance.
- Nested JARs supported (common in Spring Boot).
LZ4 Keunggulan
- Decompression speed — approaches memcpy throughput.
- Very fast compression — can keep up with SSD write speeds.
- Stable format — reference implementation unchanged for years.
- Widely deployed in databases, filesystems, and kernels.
- BSD-licensed library.
Keterbatasan
JAR Keterbatasan
- Requires a JVM to run.
- Java applet era left a security-scare legacy; browsers no longer execute JARs.
- Native code distribution (JNI) complicates cross-platform JARs.
- Modular Java (JPMS, 2017) introduced JMOD as a partial successor.
LZ4 Keterbatasan
- Compression ratio lags gzip by 20-30%.
- Not designed for long-term archival where ratio matters.
- Older than zstd, which beats LZ4 at comparable speed at slightly better ratio.
- Rare as a user-facing format — lives mostly inside databases and filesystems.

Ukuran File Umum
JAR
- Small utility library 50-500 KB
- Spring Boot fat JAR 15-80 MB
- Minecraft client ~5 MB (plus assets)
LZ4
- Text file 40-60% of original
- Already-compressed data (JPEG, MP4) 99%+ (no gain)
- Database page (typical) 55-70% of original
