Choosing a Compression Setting
Lists the compression algorithms supported by data-fabric.
Data Fabric supports three different compression algorithms:
- lz4 (default)
- lzf
- zlib
Compression algorithms can be evaluated for compression ratio (higher compression means less disk space used), compression speed and decompression speed. The following table gives a comparison for the three supported algorithms. The data is based on a single-thread, Core 2 Duo at 3 GHz.
|
Compression Type |
Compression Ratio |
Compression Speed |
Decompression Speed |
|---|---|---|---|
|
lz4 |
2.084 |
330 MB/s |
915 MB/s |
|
lzf |
2.076 |
197 MB/s |
465 MB/s |
|
zlib |
3.095 |
14 MB/s |
210 MB/s |
Note that compression speed depends on various factors including:
- block size (the smaller the block size, the faster the compression speed)
- single-thread vs. multi-thread system
- single-core vs. multi-core system
- the type of codec used
