It is just a few seconds faster. Sorry if I was not clear.

I wanted to say that it now takes some seconds of less. I think that I'm

Hi Luca,

If you're using ext2/ext3, turning off dir/file access time might help.
Edit /etc/fstab and add noatime,nodiratime on the appropriate line,
like in the example below:

/dev/hdb2   /home   ext3   defaults,noatime,nodiratime   0   2

Manon.

I wouldn't.  (Real Men use the CLI.)

Anyway... there are many lightweight file managers in Debian.  I'd

Don't use a GUI tool that's designed for small subdirectories.



Slow to ls?  reiserfs, xfs, btrfs, or the dir_index option and hash_alg
extended option of ext3.

Is the directory fast to ls, but slow to render in a GUI?  Problem is likely
with the GUI.


Sorry, it is only slow to GUI (nautilus).

How many files?

~25,000.


Don't use Nautilus, or reorganize your directory structure.

Did you also turn off "Count Number of Items" and "Show Text In Icons" in 
Nautilus "preview" preferences?

Yes. Good idea. I am however astonished that nautilus takes ~30 sec. to
open such a directory.

Slow to ls?  reiserfs, xfs, btrfs, or the dir_index option and hash_alg 
extended option of ext3.

Is the directory fast to ls, but slow to render in a GUI?  Problem is likely 
with the GUI.

How many files?  It may be better to convert to a "stepped" directory 
structure.

E.g.:
Instead of:
/home/abel
/home/alfred
/home/ada
[...]
/home/zelda
/home/zola
/home/zoolander

Use:
/home/a/abel
/home/a/alfred
/home/a/ada
[...]
/home/z/zelda
/home/z/zola
/home/z/zoolander
Or: (usually only when names are fixed-length)
/home/a/bel
/home/a/lfred
/home/a/da
[...]
/home/z/elda
/home/z/ola
/home/z/oolander

I'm most familiar with using this for ASCII names, but it can be converted to 
work with other names.  Japanese can use stroke count of the first character 
instead of first character, for example.

Accelerating directory's content's viewing: how, is directory is huge?

[Merciadri Luca]

Hi,

I have many media files in some specific directory (folder, call it as
you want). Loading the folder takes ~30 sec., even if I am using quite
fast HDDs, etc. They're all on the same partition. I have disabled
previewing, or thumbnails.

How can I do to make this process faster?

Thanks.
