Version: unspecified (using KDE 4.5.85)
akonadi comes with a mysql.conf file that has "innodb_log_file_size=64M"
which means that KDE-LiveCDs will waste 128MB of RAM just for the two logfiles.
The default log size is 5MB so there should be a very good reason to have it that big.
Additionally, wasting over 100MB per user on disks of regular installs is also not nice.
Steps to Reproduce:
du -m ~/.local/share/akonadi/db_data/ib_logfile*
This is for performance reasons. See the following page for the details: http://techbase.kde.org/Projects/PIM/Akonadi#Akonadi_needs_too_much_space_in_my_home_directory.21
See also bug 217016 for possible workarounds.
Confirm this problem, each user that contains almost empty database, eats 128 MB of logfiles (64mb in ib_logfile0 and 64mb in ib_logfile1)!
I think that size of log files must be smaller, or maybe depend of database size.
At now we can fix this via changing defaults config file /etc/akonadi/mysql-global.conf
