Subject: Re: Reiser4. BEST FILESYSTEM EVER.

Teddy,

It is a pity you don't address the full set of results, when you make
your snide comments.

Now since you have them,... why don't you make reasoned comment about
them.

You can read more here:

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).

OR LOOK AT THE FULL RESULTS:

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)
