Compression and Performance Statistics

Test Suite and Input Data

Linux Kernel 2.4.18 Compilation
- Description: A very realistic benchmark with high CPU and memory usage, mainly when forking its build. The Linux kernel compilation was run as only one process (\texttt{j1}), as two (\texttt{j2}), and four (\texttt{j4}) concurrent processes. The memory available to the system varied from 18 to 48 Mb. The case with 48 Mb almost does not have memory pressure.

- Source Code
- Input Data: .config
MUMmer 1.0
- Description: A scientific application to align genomes that has a very intensive memory usage. Almost all of its memory usage is composed of pages backed by swap. MUMmer was executed varying the amount of memory size available to the system from 330 to 500 Mb. The 500 Mb case almost does not have memory pressure.
- Web Site
- Source Code (see MUMmer web site)
- Input Data: Genome Sequences
Open Source Database Benchmark - OSDB 0.14
- Description: A benchmark that performs several database related operations using the Postgres database manager and a 40 Mb database. We ran the experiments with 24 and 48 Mb of memory in the system. The 48 Mb case almost does not have memory pressure.
- Web Site
- Source Code
- Input Data: database (from OSDB web site)
piGIMP 1.0
- Web Site
- Input Data: JPG Image
Matlab 6.0
- Description: A mathematical tool to perform numerical computations and graphics. In our tests, we used a Matlab program that computes the fractal dimensions of an image given as input. This computation may imply in an intensive memory and processing time usage. We used three different images and the virtual address space required by each of them was 80, 256 and 1000 Mb, respectively.

- Images and their Memory Usage when running the script: 1 (80Mb), 2 (256Mb) and 3 (1Gb).
- Fractal Library
- Script to compute the fractal dimension. It uses the agove fractal library.

httperf 0.8
- Description: A tool to measure web server performance. Our test using httperf performs a number of requests of a file to a local web server, measuring the number of resquest served per second. The available system memory varied from 24 Mb, which has a very intense memory pressure, to 64 Mb, where there is a very light memory pressure for this benchmark.
- Web Site
- Command-Line:
```
	   httperf --num-calls 20000 --num-conns 100000 --hog --rate 100
	   
```
Memtest 0.0.4
- Web Site

DBench 1.1
- FTP directory
- Source Code
Sort - GNU textutils 2.0
- Description: The sort program from GNU textutils aims at sorting a text file with minimal memory usage. It uses about 2 Mb of memory to sort files whose size are more than 100 Mb. The experiment results were collected with 24 Mb of memory in the system.
- FTP directory
- Source Code
- Input Data: Text File (bunzip2 first)
PostMark 1.5
- A benchmark to measure performance for small files in an operating system, by creating a large pool of files and measuring some transactions rates. This benchmark was run with 128 Mb of memory in the system.
- Web Site
- Source Code
- Configuration Options:
```
	   set number 10000
	   set transactions 1000
	   set subdirectories 5
	   set size 500 100000
	   
```

Compression Algorithms

WK4x4: is the variant of WK compression family developed by Paul Wilson and Scott F. Kaplan that achieves the tighest compression by itself by using a 4x4 set-associative dictionary of recently seen words.
WKdm: compresses nearly as tightly as WK4x4, but is much faster because of the simple, direct-mapped dictionary of recently seen words.
miniLZO: is a very fast Lempel-Ziv implementation by Markus Oberhumer. Note: support added back since 0.23pre4.
