As demonstrated also in this thread, there is a widely accepted myth that defragmenting is completely useless with Linux, and as such nobody has been really bothered enough to write any reasonably usable generic tool.
Given that modern file systems are fragmentation resistant, please explain how fragmentation is a problem on Linux.
Well that isn't a explanation. In fact the guy admits he's a KDE developer and not a kernel hacker. I was, though not any more. kernel hacker that is. Disk drivers and file systems were my focus back then. Different technology, UNIX, not Linux, but some principles still hold.
The impression I got after reading his link is he was talking about grouping related files to minimize head movement, which is not the same as defragmentation. I have to wonder how he could be a developer and not know the difference. As for interleaving, I recall when that was necessary, because the computer couldn't keep up with disk data.
Please do not take offense - but - maybe the developer is from India.
The reason I say this, is because, in Nov, my wife lost her IT job, Business Analyst, to India. Thankfully, she found another job, in a smaller company, by mid-Dec.
Gee, you could please stop this before this thread gets any worse? It got already quite pointless after about 5 mails, but this is really too much. If some people on this list feel they need to just chat, maybe there should be a separate opensuse-chat mailing list created. As I like getting straight to the facts, here are some facts for you: - The linked blog entry is from me. It can be easily recognized by it having my name in the header, just like this mail does. What makes somebody indulge in strange theories about the author's details instead of clicking the name in the blog to see the about page is beyond me. - Just because I'm not a kernel developer does not mean I'm clueless or even stupid. In fact, I usually provide evidence for facts presented in my posts, and the major factor of KDE startup time at the time of writing that was inefficient filesystem layout of data. - Just because you think filesystems are only about files does not mean it's the only thing that is read from the disk or that filesystem fragmentation is only about having each single file in a single continuous area. I explained that in the blog post. - This thread is leading nowhere anyway, as most people enjoying it seem to lack basic knowledge of facts anyway (nobody needs to care about filesystem layout today - xfs/ext4/Windows SuperFetch/ReadyBoost?) or apparently even the ability to read and understand text. - Finally, anybody's wife losing a job is no good reason to publicly offend people this way, even when that offense is hypocritically introduced with "please do not take offence". -- Lubos Lunak openSUSE Boosters team, KDE developer l.lunak@suse.cz , l.lunak@kde.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
