SubjectRe: REISER4 FOR INCLUSION IN THE LINUX KERNEL.
Date
YOU GUYS WILL LAUGH ABOUT THIS:

I forgot the all the statistics that might support the sase for REISER4
inclusion.

Well, here it all is:

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

.-------------------------.
| FILESYSTEM | TIME |DISK |
| TYPE |(secs)|USAGE|
.-------------------------.
|REISER4 lzo | 1938 | 278 |
|REISER4 gzip| 2295 | 213 |
|REISER4 | 3462 | 692 |
|EXT2 | 4092 | 816 |
|JFS | 4225 | 806 |
|EXT4 | 4408 | 816 |
|EXT3 | 4421 | 816 |
|XFS | 4625 | 779 |
|REISER3 | 6178 | 793 |
|FAT32 |12342 | 988 |
|NTFS-3g |10414 | 772 |
.-------------------------.

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:

.-------------------------------------------------.
|File |Disk |Copy |Copy |Tar |Unzip| Del |
|System |Usage|655MB|655MB|Gzip |UnTar| 2.5 |
|Type | (MB)| (1) | (2) |655MB|655MB| Gig |
.-------------------------------------------------.
|REISER4 gzip | 213 | 148 | 68 | 83 | 48 | 70 |
|REISER4 lzo | 278 | 138 | 56 | 80 | 34 | 84 |
|REISER4 tails| 673 | 148 | 63 | 78 | 33 | 65 |
|REISER4 | 692 | 148 | 55 | 67 | 25 | 56 |
|NTFS3g | 772 |1333 |1426 | 585 | 767 | 194 |
|NTFS | 779 | 781 | 173 | X | X | X |
|REISER3 | 793 | 184 | 98 | 85 | 63 | 22 |
|XFS | 799 | 220 | 173 | 119 | 90 | 106 |
|JFS | 806 | 228 | 202 | 95 | 97 | 127 |
|EXT4 extents | 806 | 162 | 55 | 69 | 36 | 32 |
|EXT4 default | 816 | 174 | 70 | 74 | 42 | 50 |
|EXT3 | 816 | 182 | 74 | 73 | 43 | 51 |
|EXT2 | 816 | 201 | 82 | 73 | 39 | 67 |
|FAT32 | 988 | 253 | 158 | 118 | 81 | 95 |
.-------------------------------------------------.

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)

.-------------------.
| FILESYSTEM | TIME |
.-------------------.
|REISER4 lzo | 1938|
|REISER4 gzip| 2295|
|REISER4 | 3462|
|EXT4 | 4408|
|EXT2 | 4092|
|JFS | 4225|
|EXT3 | 4421|
|XFS | 4625|
|REISER3 | 6178|
|FAT32 | 12342|
|NTFS-3g |>10414|
