Unix File System performance with large directories
Hi,
how does the Unix File System perform with large directories (containing ~30.000 files)?
What kind of structure is used for the organization of a directory's content, linear lists, (binary) trees?
I hope the description 'Unix File System' is exact enough, I don't know more about the file system in use there...
Regards, Dirk

I have a filesystem cache which is around 20G in size and I'm a bit perplexed as to what is in it.
I'm running Sybase on the machine with the db on raw volumes and a tempdb on a ramdisk.
My understanding is that raw volumes are not cached and I assumed that the ramdisk is not either. Am... (1 Reply)

file::spec::cygwin5.18
File::Spec::Cygwin(3pm) Perl Programmers Reference Guide File::Spec::Cygwin(3pm)
NAME
File::Spec::Cygwin - methods for Cygwin file specs
SYNOPSIS
require File::Spec::Cygwin; # Done internally by File::Spec if needed
DESCRIPTION
See File::Spec and File::Spec::Unix. This package overrides the implementation of these methods, not the semantics.
This module is still in beta. Cygwin-knowledgeable folks are invited to offer patches and suggestions.
canonpath
Any "" (backslashes) are converted to "/" (forward slashes), and then File::Spec::Unix canonpath() is called on the result.
file_name_is_absolute
True is returned if the file name begins with "drive_letter:", and if not, File::Spec::Unix file_name_is_absolute() is called.
tmpdir (override)
Returns a string representation of the first existing directory from the following list:
$ENV{TMPDIR}
/tmp
$ENV{'TMP'}
$ENV{'TEMP'}
C:/temp
Since Perl 5.8.0, if running under taint mode, and if the environment variables are tainted, they are not used.
case_tolerant
Override Unix. Cygwin case-tolerance depends on managed mount settings and as with MsWin32 on GetVolumeInformation() $ouFsFlags ==
FS_CASE_SENSITIVE, indicating the case significance when comparing file specifications. Default: 1
