Bug ID: 338402
Summary: File system cache is inneficient : too many file per
directory
Product: Akonadi
Version: 4.12
Platform: Debian testing
OS: Linux
Status: UNCONFIRMED
Severity: grave
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=757844
~/.local/share/akonadi/file_db_data/ is completly inneficient and render the
whole system slow.
Directory shoud not store more than a thousand of entry. With my multi
gigabyte mail box I have more than 900000 entry in this directory.
See
http://etutorials.org/Server+Administration/Squid.+The+definitive+guide/Chapter+7.+Disk+Cache+Basics/7.1+The+cache_dir+Directive/
paragraph 7.1.4 L1 and L2 for how to do.
thumbnail cache, git and squid use this technique.
I am tented to raise to RC severity because some filesystem does not support
this insane number of file per directory (see for instance ext3 limit here
