Clubic and JKDefrag

[Eric2]

I wonder how French computer scientists get by, when they get out in the real world? Maybe they don't?

Hi Lundholm,
I just read this morning:  http://www-verimag.imag.fr/~sifakis/

Hi Lundholm,
I just read this morning:       

Yeah, he's good.....and Greek!

The article was updated today and on this page : http://www.clubic.com/article-92386-6-guide-defragmentation-principe-logiciels.html JKdefrag is almost last. "Still 12 % of files defragmented according to the other softwares"

[haklia]

Something I do not understand: thanks to the graphic, we can see that files are defragmented, so why other softwares tell that files are still framented?
May be softwares include optimization in the 12%.

"Still 12 % of files defragmented according to the other softwares"

It's a pity I cannot read that article, I think it's French? Does the acticle say which version of JkDefrag they tested? From your one-line translation I gather that they haven't looked at the JkDefrag logfile, only "other softwares". I see something about "168 fichiers MP3", so I think they have tested with MP3 files? It is then totally impossible that JkDefrag could not process 12% of the files, only some system files cannot be defragmented. I would be very interested in learning which files could not be defragmented....

I'm French so I can explain what they said in this article.

To compare softwares, it was necessary to offer them the same score to defragment. To this end, we chose to copy, sector to sector, a very fragmented disk (69%) to another disc using Norton Ghost 12 and Smart Copying Sector. The first disc remains intact and serves as a source to revive a copy after each defragmentation. The partition used a size of 320 GB, 23 of which are used, leaving plenty of room for different defragmenters to carry out the operations of reallocation of clusters. Latest details: all operations were carried out on a hard disk Serial-ATA, Hitachi brand (HDT725032VLA360 model), running at 7200 rpm, and formatted in NTFS, a system that we feel close to that of a "user . The test computer is equipped with an Intel Core 2 Duo E6300 running at 1.86 GHz and 2 GB of RAM.

Finally we completed our tests by three measures of performance through:
A copy of a file of 5.4 GB;
The transfer of 168 MP3 files, for a total of 922 MB;
Copying various files, for a total of 9.33 GB

These transfers are made from the disk defragmented, since it is the speed of reading data from disk, which is enhanced at a defragmenter (the writing speed may also be, but this is not the Role of defragmenters). The file was fragmented 5.4 GB to 23%, and that the entire disk it was nearly 69%. The results of these tests are reported in the following table. Note that the figures presented here are dependent on our setup, it is therefore necessary to compare them only.

Note: We have intentionally omitted certain modes defragmentation jkDefrag which we seem irrelevant given the configuration of our drive to defragment.

Quality of defragmentation

Determine the quality of a defragmentation is not easy. To assess this, we conducted performance tests, as you have seen, but also cross-tests, which are to estimate, by all other software, the work of another. Thus, at the end of the disk defragmentation of our O & O Defrag, for example, we performed an analysis of the same disc with all the other tested software. Where possible, we also tested different methods defragmentation software. The results are given in this table.

First observation, 4 software are unable to defragment the disk properly. This is jkDefrag, whatever the method used, Norton Speed Disk, with all the same 31% of fragmentation remaining UltraDefrag and to a lesser extent, in its Perfect Disk Defrag Only mode, which leaves trainer 3% fragmentation. All other fare well, it means none of the other defragmenters has found a fragmented files after their passage.

Second point: the "favorite" of previous tests, namely UltraDefrag and Auslogics Disk Defrag, here are widely ranked. Indeed, if the latter makes a copy partaite, UltraDefrag is far from this result. Finally, note for pay software that only barely Symantec software to perform defragmentation disk test. This result is relative to the fact that Speed Disk is part of the software suite SystemWorks and that the defragmentation tool may not be the greatest achievement of this package of programs.

I'm French so I can explain what they said in this article.

Ah, thank you very much. I have now found the links to the next pages at the bottom of the article, I missed those at first. There is a snapshot of the JkDefrag logfile there, and it shows 4.6885% fragmentation in analysis mode. This number does not square with the 12% and 9% numbers that you quoted in your translation. Am I missing something? Also, the snapshot is about a C: disk, but from your translation I gather they tested a copied disk, not an in-use system disk. And finally, have they also measured optimization, or only defragmentation?

JKDefrag
Standard       Still 12% file defragmented according to other software

JKDefrag
Optimization fast    Still 9% files defragmented according to other software

[jeroen]

JKDefrag
Standard       Still 12% file defragmented according to other software

JKDefrag
Optimization fast    Still 9% files defragmented according to other software

The difference between these two numbers is also weird. There is only 1 defragmentation subroutine, which is used in both standard and fast optimization. So the numbers in both cases should be exactly the same.

Thanks for the tip, but Google translations (and other online translation services) are no use to me. They translate all the words, but not the syntax, and the results are usually totally unintelligable.

Indeed, there are many, but given the flavour of this exchange,
how could you have missed "entente cordiale", mon ami ? !   

Touché  !

@thm

I had to check out my dictionary for "entente cordiale".

It turns out to be a diplomatic term. It means something like "foreigners are welcome in Tour de France, if they don't win".
