**ITLCC Compression Test** s3n://commoncrawl/crawl-data/CC-MAIN-2021-10/segments/1614178347293.1/warc/CC-MAIN-20210224165708-20210224195708-00000.warc.gz (310,856 rows) Note: A deflate codec implementation is not proposed as part of this contribution. It is just a simple integration of the Java runtime environment's java.util.zip.Deflater and java.util.zip.Inflater offered as a baseline comparison. |Codec|Level|Total compacted size|Compression|Major compaction time (seconds)| |---|---|---|---|---| |None|-|5,121,804,020|-|-| | | | | | | |lz4 (aircompressor)|-|1,525,277,027|70.2%|16| |lz4 (lz4-java)|-|1,524,932,289|70.2%|13| |lzo (aircompressor)|-|1,578,220,788|69.2%|15| |Snappy (aircompressor)|-|1,595,784,200|68.8%|14| |Snappy (xerial)|-|1,604,659,551|68.7%|17| |ZStandard (aircompressor)|(dfast)|1,074,637,595|79.0%|32| |ZStandard (zstd-jni)|1 (fast min)|1,111,058,386|78.3%|18| |ZStandard (zstd-jni)|2 (fast max)|1,076,837,323|79.0%|20| |ZStandard (zstd-jni)|4 (dfast max)|1,034,994,492|79.8%|33| |ZStandard (zstd-jni)|5 (greedy)|1,021,233,357|80.1%|38| |ZStandard (zstd-jni)|6 (lazy)|1,004,341,613|80.4%|50| |ZStandard (zstd-jni)|12 (lazy2 max)|975,070,595|81.0%|225| |ZStandard (zstd-jni)|15 (btlazy2 max)|909,137,633|82.2%|446| |ZStandard (zstd-jni)|18 (btopt max)|905,353,364|82.3%|1214| |ZStandard (zstd-jni)|22 (btultra max)|903,207,510|82.4%|2406| |LMZA|1 (min)|972,730,691|81.0%|201| |LZMA|3 (default)|955,130,988|81.4%|264| |LZMA|6|911,930,048|82.2%|1260| |LZMA|9 (max)|911,929,521|82.2%|2124| | | | | | | |Deflate (java.util.zip)|1 (min)|1,227,907,255|76.0%|43| |Deflate (java.util.zip)|6 (default)|1,059,481,372|79.3%|89| |Deflate (java.util.zip)|9 (max)|1,013,628,808|80.2%|147| -- This is an automated message from the Apache Git Service.
