Re: Reiser4. BEST FILESYSTEM EVER.

[johnrobertbanks@fastmail.fm]

Lennart. Tell me again that these results from 

http://linuxhelp.150m.com/resources/fs-benchmarks.htm and
http://m.domaindlx.com/LinuxHelp/resources/fs-benchmarks.htm

are not of interest to you. I still don't understand why you have your
head in the sand.

Column one measures the time taken to complete the bonnie++ benchmarking
test (run with the parameters bonnie++ -n128:128k:0)

Column two, Disk Usage: measures the amount of disk used to store 655MB
of raw data (which was 3 different copies of the Linux kernel sources).

Each test was preformed 5 times and the average value recorded.
Disk Usage: The amount of disk used to store the data (which was 3
different copies of the Linux kernel sources).
The raw data (without filesystem meta-data, block alignment wastage,
etc) was 655MB.
Copy 655MB (1): Copy the data over a partition boundary.
Copy 655MB (2): Copy the data within a partition.
Tar Gzip 655MB: Tar and Gzip the data.
Unzip UnTar 655MB: UnGzip and UnTar the data.
Del 2.5 Gig: Delete everything just written (about 2.5 Gig).

To get a feel for the performance increases that can be achieved by
using compression, we look at the total time (in seconds) to run the
test:

bonnie++ -n128:128k:0 (bonnie++ is Version 1.93c)
