I continued my investigation and find some interresting things on the german WP forum

about the 2.8 version and 64bit server php bug due to gettext.

Also from germany this post in english:

from the author of memory_overview plugin

And a begin of solution, a modified mo.php file, from here:

http://www.code-styling.de/deutsch/wordpress-28-sprachdatei-speicherverbrauch-minimieren (the link to the mo file is in yellow under the title “Historie des Downloads” )

This file goes into wp_includes/pomo

Use memory_overview plugin, go to the dashboard to view the difference.

Since 2.5, WP give the possibility to increase php memory in wp-config, but this didn’t work for me.
